The apartment has an absolutely perfect location to explore Madrid. The only negative aspect due to the location is the noise. It’s in the middle of one of the most visited shopping streets where day and night time is a lot of noise and street music as well. We didn’t care but that also means you can’t open the windows due to the noise. As we had a very smelly bathroom as there were maybe broken pipes, we couldn’t open the windows as it would be to noisy.
These two points are the only ones that were negative at this stay. Other than that I would recommend the apartment at any time. The bed was super comfortable and the communication with Irene quickly. Check in was well organized.
