We stayed in the heart of Madrid, a stones throw from Plaza Mayor. First off the communication from the beginning was superb. They answered all questions in a very timely manner, most within 1-2 hours.
The apartment is in a great area where you are close to everything. The apartment is on the 4th floor and has an elevator. This apartment is updated very nice, clean, and has wonderful amenities. The washing machine and dryer were a welcome as we had been traveling for some time. The bathrooms are amazing and updated. The kitchen is stocked better than any rental apartment I have come across and they have a new full-size refrigerator/freezer. We did not do any cooking but it is well equipped to handle anything and bonus they have a dishwasher too.
I can not say enough great things about this apartment, the host, and the location. We give it a solid 5 stars and hope to be back again.
