I came to Philly for a conference. This is a perfect 10 minute walk away from the convention center and also very close to many attractions downtown.

Fantastic location

The apartment was beautiful and within easy walking distance of everything. The view was spectacular. The terrace would be lovely when the weather is warmer. I am already planning another trip. There are only 2 things to be aware of: 1) unloading luggage is challenging, there isn't really a good place to park 2) be aware that the main bed is a double and not a queen.

Very modern vibe. Which was confusing b/c there were no USB or USB-C ports to charge your phone(s). The dishwasher was broken and the coffee grounds were expired.

Great value for Philly city center.

Very happy with this aparthotel, just on the outskirts of the city center, good location for a lot of major attractions. Nearby parking was a breeze. Apartment was nicely furnished and in good condition. Very clean. Would be happy to return.

Wonderful location and amazingly decorated. Only concern is that on-site staff were not quick to fix issues with the unit's facilities, though support employees were great with addressing problems. Otherwise, definitely recommend if you're staying in Philly!

We stayed at a one bed room apartment for a week and totally enjoyed it. The apartment is new, well decorated and clean; there is a small but nice gym on the basement. The neighborhood is a little noisy from the street traffic at night (the windows could use a bit better insulation). Not too many restaurants or shops in the immediate surrounding but we had no problem using Uber to get around. Overall, we really liked it.
