We loved it! Perfect situation in the historical center of Porto, you can walk to all places to visit on foot (e.g. 3mn walk to the Douro river)- we only took public transportation to go to the airport.
You can find all facilities nearby: supermarket (1mn), metro station (5mn), bus or tram to the seashore, all kinds of bars, restaurants...
The apartment is cosy, nicely decorated and brand new!
The only downside is the noise: from the busy street, works on the neighbour building and neighbours if they are noisy.
However, we were so nicely welcomed by Eugenia that this downside was soon forgotten. She took the time to give us such a lot of useful and personalised advice (better than the tourist office!).
Many thanks again Eugenia, we know where to stay when we come back to Porto!
