We stayed in Porto for 3 nights in August and really loved our stay in the city. Cesar's place is well located and very convenient for getting around. The metro is a little more than 100 m away, there are lots of restaurants about a 10 min walk away and Luis 1 bridge is about 20 mins by foot. The only time we had to use a vehicle was to avoid walking to our restaurant reservation but otherwise we walked the entire time and did not make use of Metro. The apartment itself was very clean and we did not miss anything although we did not really eat there but used it as a base and spent most of our time exploring the city and eating there. The only thing of note is that there is essentially one ceiling shared by all rooms other than the bathroom, which has its own, so within the apartment the noice carries from one room to the other, which was only meant our daughter could not sleep as late as usual in the morning.... Overall it was not an issue for us and the noise level from outside is low and we slept well.
