Matteo is a great host.
He recommended some great places to eat, helped us find a good area with street parking so we didn't have to dish out $40-50 euros everyday for garage parking, and really was able to help out with all of the requests we had throughout our stay.
The apartment was comfortable and had pretty much anything we needed, including coffee. Also there was a little corner store outside of the apartment and one that stayed open late just down the street which was very convenient.
The only downside of the stay was the location... kinda.. The apartment is very walkable to all of the attractions however the apartment is in a little bit of a weird pocket where it can feel a little sketchy especially at night and that includes the square nearby Martim Moniz. We didn't have any issues personally but we did see some people get into a fight outside of the apartment.
