We felt very welcomed (loved the welcome-shot!) despite the fact we didn't meet Gonçalo in person.
The description of the flat was accurate and everything was like shown on the photos. And the location is great - close to the important metro sation (Rossio) and easy accessible even from the Santo Apolonia railway station. It's a bit chilly like in most of the apartments in Portugal if not staying in the summertime. But just take an extra pair of socks and a sweater with you and you'll be fine! :)
It was a nice stay and experience and we had no problems at all
