Alberto is a friendly host, who was always replying fast, if I was sending some questions to him.
I arrived at 11:30 PM on New Years Eve and we even had a little celebration together, that's been a nice surprise and a great start of the new year!
He gave me some good advice about Lisbon and the flat was clean.
His flat is close to a metro station. I can definitely recommend staying there.
Thank you Alberto!
