Diogo & Filipa's place is nice and spacious, same as you can see on the photos. It's at a very good location, near transport and grocery shops. Restaurants and bars are within 10-15 minutes walk. The flat is clean (not hotel level, but that's fine with me). They were very quick to respond when I had issues with the internet and it got fixed soon. They were flexible with the check-in and generally very helpful.
I was there in March and the apartment can get a bit cold, though there's one small heater. I guess in the warm months it's refreshing to get back to a cool flat after a long day walking up and down the hills.
