This apartment is on the second floor and has no lift so is probably not suitable for elderly people. It has two balconies with French windows that open on to them. You can sit and have coffee in the mornings if you are used to traffic noise but we preferred to go the 3 minutes down the road to Plaza Merced, where Picasso lived, for coffee and tapas.
You are within the historic centre so everything is within a short walking distance. The Carmen Thyssen Museum is a wonderful art gallery, The Picasso Museum is a must, and so on.
The cooking amenities are sparse; good for preparing snacks but not for family meals. The beds are comfortable and clean and the apartment is easy to sweep because of the tiled floors. The television is good and the Wi-Fi works just adequately to watch movies on Netflix.
There is a taxi rank opposite the apartment so that's handy as well.
Ernesto seems to be an honest and helpful man and we felt comfortable with him as a landlord.
