Building in a great location in Madrid, near Prado and Sol. Mar was extremely pleasant and communicative throughout the entire process, from booking to check-in. This particular unit was on the top floor (5th) of the building but elevator only went to the 4th floor. We were made aware beforehand and it wasn't an issue for us but something to keep in mind. Also, the ceilings are pretty low in the bedrooms, which probably isn't a problem for most people but we had 2 people over 6 feet. Bathroom and kitchen are small but functional for a couple people for a few days. All in all, a good place to stay.
