The apartment is nice, clean and well located right in the city centre. It has all the amenities listed in its description however the washing machine and dryer are shared amongst other people in the flat. Those are the only shared facilities, everything else is located in the individual rooms. It is a short walk to Puerta del Sol and to the main street on Gran Via.
The host has good response time and is very cordial.
The negatives of the place are the apartment is not spacious enough for three people as it was tight for my friends and I all being in the same space.
We all had to share one key which wasn't convenient at all.
The name of the apartment on airbnb shows "Plaza Espana" but it's actually located in Gran Via, each room in the flat is just named after a tourist location in Madrid.
