This was the best part of our stay in Madrid! Location is absolutely amazing and walking distance to all the areas we visited. It overlooks a quite busy square and you could hear people when the windows/doors were open but otherwise it did not affect our ability to sleep. Definitely added to our Madrid experience by having the apartment with the balcony in that awesome location. Also, the host (Alicia) was able to help us get into the apartment a little early which was greatly appreciated!
