The apartment was very clean and was exactly as portrayed in the photos. The provided amenities are very modern and in great working order!
Cláudia was a very gracious host, welcoming us when we arrived and giving us a thorough breakdown of things to see and where to eat. Her suggestions were very helpful indeed!
As already mentioned, be prepared to do a bit of uphill walking around Oporto, although the flat is close to local metro/train stations and tram & bus services.
Lastly, if you're a light sleeper the seagulls might keep you up at night - bring ear plugs!
Cheers, Cláudia!
