The apartment is overall quite a nice space, and is very well-located. It works well for a short trip to Madrid for a couple. The apartment is not as clean and well-equipped as it might be however -- for example, not all the light-fixtures were working, so it was not very light, and it was fairly dusty in places. Sergio was a decent host, and although we did not have a lot of interaction, he did make the check-in and check-out process very straightforward.
