The location of the house is pretty good. It is one minute walk from the underground and really closed to the city centre (ten minutes).
We arrived late due to flight delay, and they were very patient, answering our messages inmediately and showing us how to arrive to their house.
The first day they spent the night with us, and they organised everything so that we could be comfortable. They left their room to us and they also gave us a guide with best places to go around, to have dinner and how to deal with such a big city.
So everything was okey. Recommended!
Thank you!
