We would give this place six stars! New, modern, spare with good facilities, a washing machine with built-in dryer!!! (who knew?) and dishwasher.
Located a short walk from a metro stop with a direct line to the Madrid airport, so it's an excellent choice if you're starting or ending your voyage in Madrid. Adjacent to a lovely residential neighborhood with many nice restaurants. There's a supermarket, premium baker, pharmacy etc within two blocks.
It's close (I km) to the Barnebau, the Madrid soccer stadium. We don't know what it's like on game nights, I checked the schedule before booking.
