In general, it is a nice apartment. But there are some things that came as a surprise. If you plan to drink your morning coffee and evening wine on the beautiful balcony, be aware, that it is not big enough for 2 people and that it faces a grey wall. It is very well shot, however, the picture has nothing to do with reality.
The apartment looks big from pictures. In reality, it has maybe 40m2, for example the kitchen with living room is max 10m2. We had ants all over the apartment, the agency that takes care about the apartment was quick to respond but they looked like they had no idea about the ants. They brought a spray to kill the ants but we would have to spray literally the whole apartment since the ants were everywhere - on the floor, on furniture, even on the walls.
Porto has really beautiful apartments - I think you can find a better one that this one in the similar price range.
