The apartment is incredibly spacious and very light. The location is great, right in the middle of the historic center of Madrid.
The bed is above the living room, on a vide. Nice to have it outside of the living room, but it is a bit of climb coming down.
The bathroom is a bit dark. The biggest downside I would say is that the shower is not attached to the wall, so you’ll have to hold while showering. If you intend to stay for a longer period that is something I would consider.
For us, the location was the best and the large table and all the light in the room made remote working perfect!
