The stay at Daniel's apartment was great! First he accepted to check me in at 1:00am since I had a late flight, which was very generous of him. The apartment itself is small but had everything I needed for a long stay of 8 days, including washing machine and a comfortable kitchen where I eat almost every day. The building is located in a quiet area, 30 min walking from the cool locations like Melansana and Chueca, or three metro stops, which is also very accessible to the location. So I definitely recommend Daniel's apartment if you're looking for a quiet space to hang in and work from, without spending tons of money!
