I had a wonderful stay at Isabel's! The apartment is very conveniently located right by the centric metro stations of Sol, Ópera, and Callao, numerous attractions, and the Corte Inglés' supermarket. Despite being located in such a bustling area, the noise is not an issue because it is actually very quiet all day and night. This was important to me because I needed to read and study during my stay, and I was able to do it without any disturbance. The apartment was very clean, nicely furnished, and quite comfortable for two or three people. Also, the communication with the agency was excellent! I would definitely stay there again!!
