My 3-nights stay was overall comfortable. The room for one person was clean and everything I needed such as towels, toiletries, etc. were available. What I needed from the kitchen were also there and I was glad some bread/snacks and coffee or tea were offered.
The location isn't too far from the center and it's very easy to get on a bus or train to the touristic areas of Madrid (on foot, it was also a manageable 25+ minutes for me).
Above all, the host was easy to communicate with, helpful, and understanding. I felt relaxed in her place and the pets were also nice and calm! ^_^
Thank you, Soledad!
