We have stayed in total 4 nights, 2x2, at Eduardo E Elaine's. We really enjoyed our stay! Eduardo is very friendly and helpful. He recommended us some nice places to eat and stored our luggage the last day when we had some time to kill before our flight.
The apartment itself is lovely. It has a very comfortable bed, it's very spacious and u have a private bathroom and cute terrace to sit outside.
It's located a bit out of the city center but it's easy walkable. It lays on a hill with 2 tram stops in walking distance (around 5-10min).
