Our visit to madrid was very good, Chemas's house is very, very, very good located, walking distance to all interesting points in the city! The metro is near the house so you can choose if you want go walking or by metro.
The neighborhood is like "Bairro Alto" in Lisbon, very good restaurants and bars.
Chemas was a very good host!
He indicated all points of interest of Madrid and explaind all city in a few minuts. We staied in new years eve and Chema helps us made all spanish tradition, included gaving us grapes to eat at midnight in Portas do Sol!
We are very grateful to meet Chema!
