Absolutely fantastic place! Great location, walking distance to plaza's with lovely cafes in one direction and a little park in the other. Easy access to Plaza Mayor as well.
The space has everything you could need - the kitchen is small but perfectly stocked and the shower is great with a plentiful supply of hot water. We were checked in by Lisi, she was SO friendly and welcoming, she made us feel right at home.
10/10 would stay here again, it felt like a proper little home in Madrid.
