We stayed at Nuno's place for five nights and loved it!
Nuno made us feel really warmly welcomed, we couldn't have chosen our place to stay any better.
Excellent location, quiet building and the flat itself was awesome, clean and very cozy. I haven't got a single bad thing to say about anything.
I would definitely recommed Nuno as a host and his flat as a perfect place to stay when you visit Lisbon!
