Goncalo's place is beautiful! The location is perfect (right next to Rossio train station) and the views from his home are breathtaking. Goncalo was one of the most responsive hosts I've ever experienced and went above and beyond through the check-in process and provided a ton of recommendations and suggestions.
We did have some wifi issues in which even when we were connected nothing would load. You don't go to Portugal for the wifi, though it was a bit frustrating at times when we were lounging around his place and couldn't get wifi to work. Overall, I highly recommend Goncalo's place!
