Ezti place is the best location in madrid!! We stay for 3 night. We just walk through street and found most of attraction. It's quite small but perfectly fit for 3 people. Ezti waiting for us when we arrived to greet and tell about anything you need to know. She give us a bottle of champaine for complementary. How nice :) but if you have a huge luggage or going with elderly people, this is REAL challenge. Elevator is on progress and that cause wifi problem sometimes.
So if we came back to madrid again[with a smaller luggage :P], we will definitely stay at Ezti place again :D
