Nice, big apartment centrally placed in Madrid! 10 minute walk from palace and 30 minutes to El Retiro park. Many places to eat tapas just on the street below. The sound insulation is just ok, we could hear the neighbors occasionally and some street noise but overall a great place to spend a month in Madrid. AC was lovely. Very clean, good amenities like shampoo and a laundry machine, plus perfectly situated to easily access anywhere in Madrid.
