The apartment was nicely furnished and the kitchen/lounge was a particularly pleasant place to sit and relax. Although Tomás was away the weekend we visited, two of his friends were there to welcome us and answer all our questions. Their suggestions about where to eat and where to visit made our trip significantly more enjoyable than it would otherwise have been.
The apartment is very central. There are dozens of bars, restaurants and bakeries within a few minutes walk, a large supermarket five minutes walk up the road, and most of the city's places of interest within an easy twenty minute stroll.
You may have to put up with some noise at night. Porto is a lively city and there were a lot of student activities taking place the weekend we were there. If you're planning to be out late this won't be a problem, but if you have kids and want an early night, and especially if you sleep with the windows open, you might not get the good night's sleep you were hoping for. But then, the bakeries are really close in the morning!
