Santiago's apartment was of the best I ever been in 10 years of travelling with airbnb!
Santiago was nice and super responsive: everytime we asked for something and he was very flexible with the check in/out time.
The apartament was super clean,cozy and we felt like we were at our home,there's everything you may need and maybe more.
The position is in the heart of the city and you've got everything at walking distance (we bought the metro card but just walking we could reach every main site).We will definitely stay here when we'll visit Madrid again!
