Sergio's place is great! He was easy to communicate with. When you walk into the apartment, it feels very clean and lively! It is on a main road that leads right to the main markets and plazas, which is good if you are easily lost like we are :)
The only thing is the walls are thin, so you can hear the neighbors. It was no problem for us, but if you are a light sleeper or on a romantic holiday you might want to think about this. However, the neighborhood itself is pretty quiet, while being easily accessible to the nightlife!
There is a very friendly food market and a fresh bread store 1 minute or less walking. I would absolutely stay here again!
There is a parking lot right next to the apartment for $25 a day, which is expensive but easier than moving your car on the free streets.
