Alvaro is extremely friendly, he answered all our questions about staying in Madrid and obviously did it with great pleasure. The apartment is perfectly located next to both old town and rail station, no noise from the street comes into it. It is not so hard to climb the 4th floor and Alvaro helped us with the luggage. The flat is small but very tidy, with completely equipped kitchen and a sofa were one can sleep in addition to a bed in bedroom. Staying there was absolutely enjoyable.
