The place is very clean and calm. The self check-in is very handy (even if the use of a pin-code system takes some time to get used to and isn't always working from the first attempt)
There is a cafe just downstairs where you can get a cup of decent morning coffee for under a euro. So we didn't even use the coffee machine in the house.
There is a shelf in the common living where you can buy a bag of muesli, infusion, almonds, sun dried figs (apparently all hand made) or even tiny cute magnets out of wood with drawings of Porto sights made by one of the owners. The prices are affordable : just put the suggested amount inside the tip box and grab what you like.
So a great place overall =)
