The apartment is super central. Most sights are in walking distance and public transport (also to the airport) is very convenient. We bought a metro card which we hardly ever used...It was a lot quieter than expected (given the central location next to Plaza Mayor). At the weekends it’s getting kind of noisy at night (other days are totally fine) but as the bedroom is not facing the street, it is not a problem. We closed the windows and slept just fine. There is no car traffic in the road, just pedestrians.
The kitchen could have been a little cleaner (especially dishes and cutlery) but nothing we had a problem with whatsoever. We would for sure come again! Thanks Pilar and Felipe
