We had a great stay at Alejandro's place! The apartment is really central, you can do everything by foot. It's also super easy to reach it from the airport. The room was good for two, and a good point was that the apartment has two bathrooms (very convenient, we never had to wait for it). Alejandro was very reactive and gave us a lot of indications for things to do (like when the museum are free, thank you for that!). I would definitely come back :)
