We loved the place!! The house is located in the historic centre, everything can me managed by foot. The house has a balcony with a really nice view. There are two bedrooms, but the apartment will be small for 4 persons, unless the only time that you spend in the appartment is when you sleep.
The apartment is fully equiped, you can park in front of the building, but just for 2 hours between 09.00 - 19.00h, after that it is free and no time limit.
ORM respond quickly and Filipa was really nice and helped us with everything. She had good recommendations and we really enjoyed our stay at Porto!
