Sara and her boyfriend are very nice and very welcoming.
The room is simple but clean and fonctional (a little noisy in the morning but that's it).
I parked for free on the other side of the river (around 20min by walk from the Airbnb). And the Airbnb is around 20min by walk from the city centre. The nieghborhood is nice with a lot of shops.
I highly recommend Sara for your stay in Madrid :) Muchas gracias!
