We had a very nice stay at Isabel's place in Malasana. The apartment had everything we needed, Isabel made sure we were awaited at the apartment and provided with information, help, guides etc.
The flat has a lot of character just as the images show, there are books, audio cds, many elements that makes it feel like a home.
It is sunny and cozy and located on a quiet back-street, but it's got a good location as we walked in 10-15 minutes to all major locations, like the Royal Palace, Plaza Mayor or Buen Retiro Park etc.
Perfect place to rest and spend a few moments between city walks or on a rainy day...
