Awesome location. Minutes away from tapas street, San Miguel Market, and Plaza Mayor. And other great neighborhoods such as Chueca and Malasana are not far either.
The windows let in a ton of natural light, but as previous reviewers have mentioned, it also means sound leaks from the busy restaurants downstairs. We found this to be manageable with earplugs and the AC/Heater to provide some white noise.
Unfortunately, the wifi is weak throughout the apartment and there was not enough hot water for two consecutive showers (with 20 minutes in between). The bed is also a bit wobbly and small.
However, these were not major issues and we were willing to forgive them for a bright, clean apartment in a great neighborhood. The giant smart TV above the bed was a nice way to wind down after full days of exploring as well. Alvaro was communicative and helpful with any questions we had.
