We had a fantastic stay in Madrid. Anabel made our stay very easy. Her communication was excellent. The apartment was clean and had everything we needed. Anabel provided a high chair and a good buggy. There were toys, milk, bread, oil, coffee and tea, shower gel - all the essentials. The supermarket downstairs was very handy. The apartment is on the 4th floor in a secure, quiet estate. Everyone was very friendly. There are two Metro stations within 5 mins and you can get to most parts of central Madrid within 20 mins. Anabel ordered us a taxi to the airport and even remembered the car seats we would need which was very thoughtful!
PS. I would highly recommend a wander down to Montadero and a walk along the river. There were some fantastic play areas for kids and lots to enjoy for adults.
