The check-in was very easy thanks to Ruben's friend Rosana who welcomed us at the apartment. We felt very welcome. There was a bottle of chilled water in the fridge, oranges and chocolate. There was also milk and cereal at our disposal for breakfast. Although the flat is in need of some maintenance here and there, it was very tidy and light. Some street noise at night, but in return you get a great location right by Plaza Mayor. There is enough space for hanging clothes and the bed is comfortable. Another plus was the map of Madrid which was provided. Definitely recommended!
