What a fantastic apartment in Madrid! We had a very large group of travelers, total of 8, and we had room to spare! The apartment is very comfortable, well stocked and the location is perfect for walking or taking the metro to any of the major sites. We ran a couple of days in the city gardens and along the river. There are plenty of restaurants near by.
The beds were comfortable, very quiet and perfect for us. We arrived during a major heat wave and the AC was a god sent for us.
I would highly recommend!
