Juan easily described how to enter the flat even he could not be at his place in person. Room and bathroom seemed recently renovated and were very clean. The room was lockable by a electronic key system - very easy to handle. The flat is located directly in the old town giving access to many sights by foot.
Juan was extremely friendly, we still had a nice chat after he returned at night. He wanted to make sure I was fine. Even he had maintenance workers in the flat he found time for me and my needs.
I felt welcome and at home.
I can clearly suggest to stay at Juans place.
