What an awesome location! And a beautiful flat. Even though it’s loud at night at Plaza Mayor, as soon as you close the balcony doors, it was perfectly quiet.
The only downsides was it was quite warm in the loft where the bed is and the shower is really small. Jonás, who welcomed me to the flat, was wonderful. There was only a bit of poor communication when I left about a missing item, but it was cleared up.
Also I took the bike tour the same people who run the Airbnb offer and it was really great.
