We got in quite late (around 1am) and the host was there to greet us let us in show us around. There was some wine and drinks in the fridge which was great. The Wifi was great too! The place is quite small but fine for 3 of us. The hot water does get lukewarm/cold after the first shower but it was ok as it was very hot in Madrid. The A/C worked perfectly. There are towels provided which was great! Also it is so easy to find, literally right next to Callao station and about 5 mins away from Plaza de Espana.
