We were glad to stay in Helena & Pedro appt. Everything is like described, location is really cool. 15minutes walk to city center, a lot of restaurants and places to check. Helena is proactive, responding really quick.
Apartment is places in second floor, and stair is really sharp, there is no lift, etc, so be patient about.
House is not new, there is wooden floor, so you will hear neighbors on top sometimes.
In general I like our stay.
