Nice apartment with a view!
We stayed at Carmen's apartment for 5 days. The flat is exactly like on the pictures, we especially loved the bath. The location is OK, the train is hard to hear, calm and quiet neighborhood. Metro is also not so far, maybe 10 minutes walk and the bus stops right before the house. The Rio Madrid walkway passes near the house, it's ideal for a long run! :)
Communication went well, Carmen responds fast. We liked Madrid a lot, we recommend her aparment everyone, who doesn't need the buzz of the city, but want to reach fast the the center.
