We had a really nice stay at Eduardos apartment. It is very central, so you can reach everything by foot. We had a very nice welcome and were told about the city and given loads of tips to explore Porto. The apartment is very clean, and since we stayed for a week Eduardo organized a cleaning for in between which was lovely. The bed is comfy, and luckily theres an AC, so no need to open the windows at night as it can be a little bit noisy. Also, i would skip the restaurants in the very busy areas around the rivers and try some small places not far from the apartment, we had some good experiences there. Can really recommend this place!
