Our stay at Karem was very nice. Karem doesn’t live in the flat but someone comes to clean the apartment everyday. We really appreciated how clean and organized the flat was. The room is a bit loud because of street traffic so earplugs are necessary. There is everything you need in the kitchen to cook easy meals. It takes about 25 min to reach the city center from the apartment (PS: the streets are very steep in the area)
I definitely recommend Karen’s flat for a cheap stay in Porto
