Nice, clean place in a quiet neighborhood

We stayed here for 7 nights visiting family right here in Midtown, and it was exactly what we were looking for. The unit was clean, well appointed, and the neighboring units were quiet for the most part. We felt very safe in the neighborhood, even though a couple of the adjacent houses are undergoing renovation and looked a bit rough. Plenty of restaurants within a short walk. Great job, we'll be back for sure!

Charming 1-Bedroom Gem in the Heart of Midtown Sacramento

Just returned from a one-night stay at this nicely renovated 1-bedroom apartment while in town for work meetings, dinner with my brother, and lunch with a longtime friend. I couldn't have been more pleased with my Midtown experience!The space has been thoughtfully updated with modern appliances and furniture while maintaining its charm. The kitchen was fully equipped for preparing meals, though I didn't need to cook with so many fantastic restaurants within a 10-minute walk. The bedroom featured a comfortable mattress with hotel-quality linens that made for a restful night's sleep.Location is a standout feature here - perfectly situated in a walkable neighborhood. I enjoyed exploring the area and loved being able to walk to dinner (Zocalo Midtown) and morning coffee (Seasons, in the CLARA performing arts building) without needing a car.Check-in was seamless with clear instructions, and the host was responsive when I had a quick question. Everything was spotlessly clean upon arrival.Will definitely book again for future visits to the area! Perfect for a solo traveler or couple looking for a comfortable home base in a great part of the city.

Beware! Not safe. Not clean

We use vrbo a lot. This was a first. Please book with caution. The property is in a bad neighborhood, was not clean and unsafe. Within 15 minutes of checking an individual tried to break into the site through bedroom window. We contacted the owner and they stated that there is fake cameras outside that would keep us safe. We left property and booked a hotel. Owner denied refund. Please be cautious with booking site very unsafe and filthy.

Not a good location

The listing is very misleading. The location was not as advertised. Previous guest had problems of people breaking in. We contacted the host as soon as we got there and told him the dead bolt would not work on the door going from the bedroom to the ally. We were told not to use that door. The lot next to the property was vacant and bad shape. The other adjoining property looked like it was soon to be vacant. We ended up leaving the rental and booked a hotel which double our cost for lodging. Hoping the future guests do not have the same experience we had.

Perfect home for Sacramento stay

The apartment is comfortable, has a well supplied kitchen and I’d very convenient to the Midtown restaurants and B Street Theater. We walked everywhere except the River Cats game. My only complaint is he Smart TV does not work well. I attempted to stream from two apps which was frustrating and extremely slow. The TV would continuously buffer, split the screen into pieces such that it was almost impossible to watch. I contacted the management, but they simply didn’t care and offered no solution. I believe the TV or internet need an upgrade.

Pontos positivos: Limpeza, check-in e localização
Property was clean, kitchen was missing some basics. Entry way is very tight. Parking space is so tight you cannot actually get out of your car when pulled fully in. Back door access was great for loading but being unable to lock it from the outside was annoying. This unit was selected as the unit with good accessibility- it was not. Steps to both entrances & very cramped parking meant it wouldn’t be able to accommodate a mobility aid. Once inside the unit was moderately accessible except for a tiny bathroom & a very tall bed. My wife was supposed to travel with me & at 5 feet tall with a mobility aid, they wouldn’t have been able to easily use the bathroom & probably couldn’t have gotten up onto the bed. The neighborhood is technically in midtown but isn’t that close to very many walkable restaurants or cafes. The alley access appears to be a usual hangout for some neighborhood people- maybe homeless, maybe just under employed. The host badgered me two days before my stay in the late evening for copies of my ID and photo, long after regular working hours to the point where I was concerned that they had been hacked. A call at 8:30 pm pacific time from a Tennessee phone number is not comforting to say the least. Since they could have waited until morning & still gotten me before my trip, it was unnecessary & annoying as well as causing me to think maybe it was fraudulent. Probably won’t stay in a property owned by this host in future.

Charming apartment in Sacramento

We had a great time staying in this incredibly charming apartment downtown. It was the perfect size for the two of us and had all we needed for our four day stay. We were close enough to walk to the convention center each day, along with restaurants and nearby attractions. It was the perfect spot for our Sacramento home base.

Excellent Location & Apartment

We extended our stay in Sacramento by 1 day, and moved into this apartment from an upstairs room in the same house. The downstairs apartment was perfect! The living space was layed out well, with a desk in the Living Room that came in quite handy for doing some work from home. The apartment was clean, and the kitchen had everything we needed to cook from home. The location is PERFECT to walk anywhere you needed to go in the mid-town area. We are definately interested in renting this apartment again!
