We booked the flat in this amazing city for 2 people - theres a possibility for a third person which in our opinion is only possible if visitors are a couple plus one, double bed is quite small. For 2 pp. It was good, small kitchen with anything needed for some days, bathroom with washing machine.
Mercedes and her little daughter were nice, we had some problems with reaching each other before checkin though. Another thing was a kinda weird smell in the flat, which can be fight with some candles. The flat has a great position, all of the city can be visited by foot.
