The apartment is just great for 2 couples/friends who wish to explore Madrid. The location is very good, ten minutes walk from the center - going down to Lavapies metro can be a bit tricky (neighborhood) but I would say the area is safe overall. There’s a bar right below of the apartment, so it gets really noisy in the weekend, but for us it wasn’t any issue.
Apartment was clean and very stylish, Daniel was prompt with our requests and we had no issues at all! Definitely recommend the place!
