If you are looking for just a room to sleep in then this place is alright, although it's not near the city of Porto. Heating isn't great so if you're coming during Winter then the room will be pretty cold. Andrea responds quickly but we did not find ourselves welcome at her place.
Check-in was awful as we had to wait for 2 hours outside the apartment complex as the instructions were confusing and she sent a family member to pick us up who was 1 hour late and only spoke Portuguese. Even tho we were in plain sight, just 5 meters from her door, we were blamed for not being at the right address hence delaying check-in.
Because of these reasons, we ended up cancelling 4 of the 6 nights at her place and finding a new airbnb flat instead.
