Álvaro is truly indeed a superhost. He's just incredible I hardly met someone as nice as him. If you have any problem don't worry as he's here. He even gave me some solar cream to survive under the burning sun. His place is really great and very cosy. It's in the very center of Madrid so you can go everywhere by walking. Moreover, as if it's not enough, the metro is right in front of his door. If you're not satisfied with this, you never will be.
I recommend him a thousand times!
