Communication with Natalia was great and the check in worked properly. The house is located in an area within a walking distance to the train station (around 30min) and the main attractions of Madrid (around 30 min). The house is cute and new and the bathroom is awesome. Sheets and towels are clean and nice. The wifi works fast. If you are a couple, just using the inner room, the apartment is amazing. However, the other room, the one facing the street, was quite noisy while we were there, (we may be unlucky...)
