I highly recommend Daniel's apartment if you are staying in Madrid. The location is awesome - down the street from a metro stop on one of the main lines, a 24 hour grocery store at the corner, and numerous restaurants and stores nearby. Despite all of the convenience, the area was still quiet at night and peaceful.
The apartment has every appliance you might need along with the supplies to use them - refrigerator, freezer, washer, dryer, stove, dishwasher, nespresso coffee machine, etc.
The apartment was especially clean and well appointed. A good amount of towels were also provided.
The apartment also has a large ceiling mounted air conditioner in the living room that is quiet yet powerful. It allowed us to sleep well during some extremely hot days in Madrid.
Daniel's partner, Nataliya, greeted us and was extremely friendly, helpful and warm. Daniel was also very friendly and easy to communicate with whenever I had a question.
We really enjoyed our stay and would definitely return!
