The apartment is very nice. The only problem we had was with check-in and we have lost almost 3 hours for that. First, you need to fill the form with personal information for every person in reservation, then choose in which office you will pick up the keys, you need to park car in the center of Porto, go to Porto consierge office, take car and drive to the flat. There were found out that a remote for the garage is not there. We called them and they said they gonna check it and never called us back. Luckily we discovered that garage can be opened from inside.
Overall, the flat is great, master bed is amazingly comfortable, there is welcome wine and coffee capsules for the start.
Check-in is painful and waste of time if you only come for a day or two.
