First of all Montserrat is very-very-very friendly person. She gave us a lot of useful hints including where to watch free flamenko show, which we enjoyed very much. Despite the room is a little far from tourist center, there is a good bus connection, also you can get to city center simply on foot in about 20-30 minutes. Also there is a big amusement park not far from the appartment (about 10 min walk).
The appartment itself is really nice, very clean, you can find everything you need in the kitchen and bathroom.
Recommend it both for short and long stay!
