The appartment is very well located and Melvin was very kind. However, some equipments didn't work and there was a short power cut but this was completely forgotten thanks to the host's reactivity as he offered a solution in the next 5 minutes. We also appreciated the flexibility as we arrived around 1 a.m and Melvin was waiting for us. Note that the late check in is charged at 20 euros but most airbnb's dont offer this service. At last we recomend this appartment to anyone who wants to enjoy Madrid. All the main attractions are at walking distance.
