The best part of the apartment was definitely the location. It was on a quiet street, but was just a few minutes walk away from all the festivities that happened at night. It's also very close to some tourist destinations, restaurants, and a good grocery store. Juan was a great host too and communication was easy. Wifi was very reliable and fast.
The apartment itself was a little different than what we expected. The photos show a bright, well lit apartment but in reality it is fairly dark with limited natural light. The size was what we expected but the roof is quite low in the loft. The biggest issue was that the apartment was extremely humid, even when it wasn't very humid outside. Even leaving my clothes out made them feel a little bit damp. There were fans, so it wasn't too hot but it didn't help remove the humidity. Also, be aware that the washer/dryer is in his own apartment, not in the unit. I gave him my laundry and he kindly washed my clothes for me, but when I got them back from drying in his apartment, they smelled of cigarette smoke.
Overall we enjoyed our stay especially given the convenience of the location and Juan's hospitality.
