My mom and I stayed in Gonçalo’s place for 3 nights, and it was like staying at your friend's house. Communication with him has been very timely throughout. Check in was very easy and I very much appreciated him heated the place prior to our arrival!
Gonçalo is super nice - gave us an overview of the city and other tips, and answered many questions we had. The location is great - pretty much walkable to majority of the attractions in the city center, yet quiet at night for good night sleep. Easy to access to transportations as well.
