Sonia and Pedro have a beautiful apartment in a perfect location. The windows open up to a very cool pedestrian square with restaurants and cafes. It's less than a 5 minute walk to the river and other parts of the city are very accessible as well. Pedro met us at check in and was very friendly and offered lots of great restaurant suggestions.
We chose to sleep with the windows open as there is no air conditioning and the outdoor temperatures were great at night. Note that the square outside can be a bit noisy at night- this didn't bother us as we slept through it, but light sleepers may have issues if sleeping with the windows open. We also got lots of mosquito bites from leaving the windows open. This is not to discredit this great apartment, but just something to keep in mind if you plan on sleeping with the windows open.
