This apartment is amazing! My friend and I booked it for 16 nights and we did not have one problem or incident. The apartment is perfect for two couples and it is in a great part of the city. The neighborhood is very diverse and lively but above all, extremely safe. We had to check in at about 1:00 am but that was not a problem. The only downfall was the five flights of stairs with the bags. However, it is well worth it for the value of the apartment. I would definitely be staying here again next time I come to Madrid.
