Two of us (couple) stayed here for a little over a month.
PROS
The casita is nicer than the pictures show. It is very roomy in the dining/living room, and the courtyard is great. The study/office on the first floor is pleasant and would be just fine for one person. The master bedroom and bath were fairly large with a large deck. The upstairs bedroom is fairly small, most suited to one person. The house is very open and airy, which we needed during our visit, as it was quite hot part of the time.
The WiFi in casita worked well, enough to stream videos. There is a phone provided with free calls. Just about everything in the house worked. The coffee-maker was missing its basket, but we improvised. The kitchen is well-stocked. It was also wonderful to have the small washer/drier. We did not use the dish washer as Robert said it was finicky.
The location is good, but noisy. It is about a 15 minute walk to the Zocalo (city square) mostly on pedestrian friendly sidewalks or streets. There is also a very nice/all-inclusive/inexpensive market open every day about five blocks away. That became our go-to market.
We had an easy time communicating/dealing with Robert before departing the States and during our visit. Amado, the on-site manager was nice, but we saw little of him. Amado's father (also Amado) picked us up at the airport on our arrival. He is a bit expensive at $35 to $40 for an airport transport. He also took us on few out-of-town excursions at a charge of $15 per hour.
CONS
It is noisy. There is a very busy street about half a block away. Mexico is known for barking dogs and we had lots of them at all hours of the day and night. The nights that it was cool enough to close the bedroom windows, it wasn’t too bad, but when we had to leave them open for air, it was loud. Do bring ear plugs. The doors/windows are on tracks and designed to be completely opened. In reality, although they opened enough, we never got them all the way open as the tracks were very sticky. Do be careful of fingers/toes. There are lots of ways to catch them in the doors when opening/closing. The top floor bedroom is the hottest.
Finally, this is a Mexican apartment with the usual funky things. If you are used to Mexico, nothing will surprise you and you will find it delightful. If you are used to 4 star hotels in the states, you may think that the craftsmanship is not quite up to par. We enjoyed our stay and would stay here again.
