I spent a month in this apartment so I got to know it quite well.
Pro - My number one concern is always safety, and this is a very safe building and area. There's a large gate in front that you need a print scan (or card) to enter and then there's another security door inside by the front desk. Finally, you need to scan your fingerprint (or card) to get the elevator to go up. My second priority is comfort and convenience. This is a great location, just a 10 minute walk from the Masaryk/Horatio area of Polanco and there are 2 grocery stores just around the corner. Lots of available restaurants, coffee shops, bakeries, etc. The wifi, TV and washer/dryer all worked well (although I used an ethernet cable rather than the wifi). My third priority is price and although it is a very small apartment, I feel like I got a good deal here considering the location.
They let me register early before moving in (left and went next door to the YMCA for coffee). Went I got into the apartment one of the first things I noticed was that 2 bubs were burned out - I texted them and the next morning Angela came by to replace them (it was already too late the first night).
Con - As is evident from the pictures, this is a small place and much of the front room is taken up by that table. In the kitchen, the refrigerator door does not fully open (it hits the opposite wall) and the exhaust fan (if you are cooking) is very noisy. There's a small balcony but you cannot walk on it because of the serrated edges of the cross beams (they need a rubber mat - I noticed one of the rooms on the floor above has a mat on their balcony). Also, although the location is excellent, it is on a very busy road and quite noisy (I actually like having background noise, so it was OK). The furniture is old and well-used: 2 small end tables are falling apart (I tried to move them and the ends came off).
