Our stay was great, the location of the apartment is ideal and the self check-in was really useful as we arrived in late from our flight.
The apartment itself is beautiful and the communication with the host was super efficient and everything that was in their control was perfect. The air con was a lifesaver and the bed was comfy.
However, we did have a couple of issues with noise from other apartments and construction so bring earplugs.
Would definitely recommend for a short stay in Madrid. Thanks very much.
