Once we overcame the surprise of the rather neglected street appeal of building front and then stairwell, the apartment itself was light and airy. It is not spacious but we had ample room for the three of us. Its equipped with bedding, towels and kitchen equipment and very clean. Its advertised for 6 people but two would have to sleep in the lounge/living area which we felt would make it rather cramped: its doubtful that the hot water supply would last for six showers. The couch is very comfortable. The large terrace doors are a feature as they let in light and air and provide a view over the trees and streets below. They are double glazed, which kept the apartment warm during cooler days.
The location is excellent. This makes the apartment a real winner. Very close to Plaza Sol and even closer to Plaza Mayor, within easy walking distance of many of the galleries, museums, eateries and shopping areas.
Unfortunately we did not get to meet Kristian on either occasion that we stayed at his apartment but he was responsive to messages.
