I stayed at Luis Xavier's apartment for a week, and had a decent experience, but with a few issues. Check-in was mostly OK, but the lock box code I received in the app wasn't correct, and I also wasn't told which lock box to open, so I had to call Luis Xavier for help. At my time of arrival, the wifi was absolutely terrible. I was a little surprised when I mentioned it and was told to call the Internet provider myself - First time I've ever had to do that in an Airbnb. After that, the Internet improved a fair bit - apparently on its own - although it still wasn't exactly great afterward. Otherwise, the rest of my stay wasn't too bad. The apartment is small, but is designed to make good use of the space, and has a lot of amenities for its size, including a good kitchenette. The bed was comfortable. The building seems secure, and the rooftop location is quiet and lets in a lot of sunlight, which was nice. The bathroom had some water issues - The sink barely ran at all (I often washed my hands in the kitchen sink), and the water would occasionally cut in and out during showers. (I didn't complain about the water during my stay, so I don't know if it could have been remedied.) Communication was decent - Responses were mostly quick, but several of my questions never got answered. Overall, it's a mixed bag, but considering the location, you won't get a better deal in La Roma if you're paying what I paid.
