The flat is nice and cozy. Location is convenient – near metro station and about 15 minutes (walking + metro) from city centre. Nearby are couple good grocery stores (Lidl and Pingo Doce) and cafes.
Place itself though not very big is smartly organised. Kitchen has all the necessary utensils and equipment to cook – teapot, microwave and toaster are hidden in cupboard to keep the precious cooking surfaces clear (to have space to prepare food). Bedroom, bathroom and hallway are also fine.
Maria has always been responsive and helped with local tips. Cherry on a cake was a bottle of portwein and local pastries as a welcome gift :)
Bottom line – the place is perfect to stay (both short-term and long-term) if you want to explore beautiful Porto.
