Diogo's studio flat is situatated in the perfect area in Porto -- off a main street and within walking distance of most of the inner city. The flat is in an older, classic apartment that is nicely kept. The jewel of the rental is Diogo. His heritage is rooted in Porto and he is enthusiastic about the city and gives his guests insightful tips about the city along with detailing the history of the city. The only problem -- and it is obviously temporary -- is that at the time we were there (early November 2017) there was renovation work being done in the building next door. Hammering and drilling started at 7:30 in the morning and ended at 9:30 at night, except for Sunday. As we were out enjoying ourselves in Porto, it hardly mattered to us. But if it is a concern, do ask Diogo if the work has been completed or not before renting. That said, I couldn't recommend Diogo's flat any higher. Great place, great host, great value, great city.
