We booked this 'luxurious' apartment for a special occasion for four friends, unfortunately, we had nothing but problems here - the only thing that is luxury is the price. When the four of us checked in late the first night only two bedrooms were made up and there was no spare linen. The mattress covers on the other beds were so stained we had to spend the first night uncomfortably sharing two small double beds. Then, in the morning we awoke to find cockroaches in the hall and shower. Once we reported this the host did make up two more beds and sprayed the shower with insecticide. Although this meant we all had a bedroom, this did not stop the cockroaches for the rest of our stay! It definitely isn't luxury, many walls are covered in scuff marks and stains, the quality of the furniture is poor. The bath and shower rooms have scuffed woodwork and mould around the bath seals. Many of the electric blinds also don't work.
There is a very dangerous staircase here, completely unsuitable for children or vulnerable adults. We left the light on during the night as there is basically a 'hole' in the landing at the top of the stairs and which is an open staircase with no bannister, an accident waiting to happen. We were advised that guests often put furniture around the 'hole' to ensure no one fell down it!
Two of the bedrooms are right next to the lift shaft and there is construction work all around the apartment. It made for a very noisy stay, day and night. If you want a luxury stay in Porto, look elsewhere.
