Everything was simply great at Elizabeth's. Me and my sister enjoyed the stay there very much.
Our flight was a little bit delayed, but Elizabeth's husband waited for us at the subway to give us a lift. He was incredibly nice, he even took us to a nearby restaurant and asked them to fix us something to eat, as we were very hungry and it was 10:30 p.m., the supermarkets were closed. The next day we met Elizabeth, who invited us to her house, showed us the place and brought a touristic map for us, showed us also places to visit in Madrid, gave us interesting tips and tricks and even took us to the train station by car - and, in doing that, she drove through the neighborhood, explaining how to get home back, where was the mall, the restaurants and so on. Her hospitality was amazing until the end of our stay.
The guesthouse looks exactly as in the pictures, the views are fantastic, the house is close to the train station - a ten-minutes walk - and you have just 3 train stations until the center of the city.
We would definitely recommend the place and come back here, maybe in spring-summer, as it was a little bit cold now.
