Hotel Riu Plaza Espana is an excellent 1956 built, but modernized recently Madrid hotel. I stayed 4 nights. Hotel has 27 floors, including an exciting 27th floor rooftop bar with the best 360 degree views in all of Madrid. I appreciate that hotel security is provided against people just coming and going by requiring use of room key cards to access elevators. The rooms are pretty sound proof because this was a well-built building. Breakfast was very good with eggs, potatoes, cheeses, meats, breads, yoghurts, pastries, fruit, coffee machines. This hotel is well situated in downtown part of Madrid right on Grand Via, with a subway stop located right at the hotel. I highly recommend this hotel. I loved it.
