The location of the flat is very good and the roof top was very nice.
Although we knew that it is in a lively neighbourhood we would have preferred to know that there are 2 Night Clubs Right next to the Building which Makes sleeping difficult (Even though we had earplugs). If clubbing is why you are going to Porto the flat can Not be located better.
Important to know is also that the bathroom and bedroom are actually one room so Not much Privacy possible.
