Maria's apartment is very clean and stylish and well set-up for a group. We were 3 couples, and we were grateful to each have our own room and bathroom. The large, open living space is an especially great feature, and the couch is super comfortable. The apartment is situated on the top floor (penthouse), with the rooftop pool just above. We only made it into the pool once, but had a great timing hanging out there when we did. The pool is definitely a huge plus with this place. The location is in a safe, funky neighbourhood, with many great restaurants and sites within walking distance.
However we unfortunately dealt with some issues during that our stay that individually weren't so bad, but altogether added up to detract from our experience and would deter me from staying here again. When we arrived at 1:30 am the power was out due to an earlier storm, so we had to walk up 11 flights of stairs with our luggage and the apartment was completely dark. Because it was so late, we just got settled in the dark and went to bed. Thankfully the power was restored late the next morning. Then later that week the elevator was being serviced and we again had to use the stairs (no advance notice was given). The one bedroom without an ensuite only has a double bed despite the listing stating its a queen bed, and it's VERY firm. So firm that we often ended up sleeping on the couch instead. The keypad entry also wasn't working well while we were there, and one night when we came home late it wouldn't work at all. I had to call Angel and show him via video that it wasn't working, so we sat on the stairs while we waited for him to bring us a key. There are a few other small things related to towels, information provided, etc. that the host can easily remedy that would make their guests' stay easier, hopefully they will consider our advice.
All that said, Maria and Angel were responsive when we reached out to them on a few things, and did what they could to help. Ideally though there would be less communication with the hosts, if more information is provided up front.
