We really enjoyed staying at Isabel's place. It was a great space for the three of us, it was clean and comfortable, the shower was hot and we had everything we needed. We loved the balcony, it was so peaceful and relaxing to sit outside in the sunshine in the mornings.
The appartment is in a good location, everywhere we wanted to go seemed to be less than 20 minutes walk, and there are lots of interesting bars and places to eat nearby. We liked Madrid very much and hope to go back soon.
