We had a wonderful stay here! The apartment is in an excellent location-- walking distance to plaza mayor, palecia real, la latina, and all the museums (though it is faster to take the subway or bus to those, which is an easy ride as well). It was also easy to get to Moncloa station for a day trip to segovia.
While close to tourist attractions, the apartment is not in a touristy area. It is fairly quiet (it's a city, so there's always noise, but nothing excessive).
The amenities were very nice. We appreciated there being soap and shampoo, as that cut down on packing. We were glad to have access to a washer because that also helped us cut down on packing. We appreciated there being coffee, which we made some mornings.
Maria was communicative and kind. We arrived before we could check in and Maria let us come by and drop off our bags early.
Overall, an excellent location to stay for two adults.
