Carmen is really nice. I only speak a very little Spanish and Carmen speaks a little English (better than my Spanish 😁), but we communicated really well. Everything looks the same as pictures. Bedroom and bathroom are very clean. I didn't use the kitchen & living room because I was out exploring Madrid most of the time.
Not the closest to Centro, but close to public transport. 2 stops to Atocha + 1 more stop to Sol (Central of Madrid).
Carmen is very helpful to lead me with how to use the public transport.
