This is a great little apartment in a very cool, hip neighborhood that is walking distance from all sorts of awesome stuff. No wifi on site, but there's a wifi cafe that opens early in the morning one block away. Apartment has good AC and a nice kitchenette with everything you need. The bathroom is a bit cramped.
Hostess provided lots of recommendations and offered to hook us up with tours, etc., and was generally very responsive prior to our arrival. The property manager when we got there (Mauro) was also very friendly and helpful, and accessible when needed.
The apartment is in a complex and seems very secure; you get a key ring with four different keys, one each for the main entrance to the complex, a private courtyard accessible to you and one other apartment (no one was staying in that one while we were there), and then a metal gate and main door to your apartment.
