This is a well-located apartment, within walking distance of the Museo Prado & many sites in Old Madrid. Apartment is very small & compact, with a good bathroom & very comfortable bed with good quality bedding.
However, the kitchenette needs a makeover & lets it down. The cooktop, oven & washing machine are all in poor condition compared to the equipment in all the other Airbnb's we have stayed in. A bit more attention to detail would be appreciated, e.g, there was no plug for the kitchen sink, which made washing dishes very difficult. There was a lot of noise within the building late at night while we were there, so bringing earplugs would be a good idea.
