We are 100% satisfied with the stay at Leonardo's place. The house is very big and spacious, located in a quiet neighbourhood close to two metro station and at walking distance from some of the most famous attractions of Barcelona (Casa Battlò, Pedrera, Ramblas).
We shared the bathroom with another couple: everything was always super-clean and tidy. There is also a small kitchenette where you can have your breakfast (Leonardo provides two coffee capsules and 2 plum-cakes a day per couple).
You are given the keys of the house so you can go back and forth at your ease.
Leonardo was willing to give some very useful suggestion about bars and places to visit and was eager to help with reservations.
It's been our first experience with Airbnb and we are completely satisfied with it. We would strongly recommend Leonardo's house.
