The stay in Porto was PERFECT! Dino and Ines waited for us at 1 o'clock in the night (because we landed shortly before midnight) and it wasn't a problem for them. They welcomed us with a bottle of Port wine, a delicious cake, fresh bread for next day breakfast. There was coffee, tea and bottled water we could use for free. The apartment is big enough for a couple or family with a child. It brand new, truly modern equiped, well designed interior! We believe the apartment will be occupied every day. It is located on 2nd floor and the front door and the apartment door are opened by code you receive via message shortly before your arrival (it is really cool not to think about keys when you walk through Porto all day long). The apartment is truly well equiped: kitchenette has all you need to eat, even cook on your own; bathroom with shower gel, shampoo, etc., hairdryer.
The Wifi works perfect, there is TV (we didn't use it at all).
AWESOME! BEST PLACE TO STAY IN PORTO!
Last but not least - the place is only 5-7 minutes walking from the metro station (you travel there by metro from the airport without any interchange) and it's also about 10-12 minutes to get on foot to City Centre (square with City Hall) and maybe 20 minutes max to get to Sao Bento train station where you can start trip to any other place in Portugal.
