I spent 4 months here, so my experience might be different from those staying more temporarily.

Location: both a blessing and a curse. it's extremely convenient for public transport, particularly for buses that go directly to the main bus terminal, and a large number of restaurants and shops are within a block of it, but because of the commercial nature of the neighborhood, it's quite noisy.

Apartment: The walls in the apartment are paper thin--you can hear EVERYTHING going on within the apartment itself as well as from the street--so I was often awoken at 5am starting Thursday nights through the weekend by drunken revelers being generally disruptive. Aside from that, it was spacious and well-equipped. Both rooms have air-conditioners and heaters, and both work relatively well.

Host: Gabriel's office is right across the street from the apartment, so that gave us a lot of peace of mind in terms of issues arising or just every-day necessities. Make sure to ask Gabriel about the currency/exchange rate situation. Gabriel is very friendly, but somewhat unreliable at times. Communication would be great, but follow-through would be more hit or miss. For example, there were various instances where we needed someone to come by for maintenance or other issues, such as a leak on the toilet, and they would not show up for the agreed-upon time, or even day.

Overall, would be a great place for a short-term stay and location is really hard to beat.
