Perfect location! At the city centre, near Puerto del Sol. Everything (restaurants, shops, etc) are in walk distance. We had 2 days in Madrid as traveller and we walk almost every location from home. When we tired, we went back to home for rest easily.
Kristian was always in communication with us from weeks before until leave. We didnt see him but we talked via message. We didnt have any problem to find the home or entrance. His friend met us and gave info about home. Kristian told hints about city, dinner, etc.
There is a little pretty balcony, we chilled there at nights. Home is big enough for 4-5 people. Everything is working fine like fridge,AC,heater. Kitchen and bathroom are fine and clean.
I exactly recommend this home for city travellers and groups, especially who wants to enjoy and live in city centre.
