We had a fantastic stay at Daniel's apartment! For two couples, we loved having a 2-bed/2-bath. The apartment is extremely clean and spacious. It's in the absolute best spot for all the touristy things to do in Madrid. It's right next to a metro station and by the best pastry shop in Madrid (La Mallorquina). The self-checkin process was flawless and we were so happy to have a washing machine. Two things to note : 1. Because it's in such a good location in a city that never sleeps, the street below is very noisy late into the night. One of the bedrooms will be loud. 2. There is very little hot water. We split up so that 2 people would shower at night and 2 would shower in the morning and still didn't have enough for 2 quick showers. Honestly we feel the benefits outweigh these downsides and recommend this for anyone coming to Madrid!
