We had a great few days in Porto and Carlos Augusto's flat is in a superb location for exploring all key areas of the city - Ribeira, Aliados, the city's main nightlife area, as well as the buzzing / more hidden area just north of the university. Not to mention the Clerigos tower and Livraria Lello being just a stone's throw away. The layout is a bit odd, being a U shape around the stairwell, in effect, but we spent so little time in the flat that it didn't bother us too much, and the living area was nice, overlooking the rooftops. Having two toilets was a real bonus. We did find it noisy at night - and even in the early morning, presumably when late-night revellers headed home. A combination of earplugs, earphones and making use of the sofabed in the living room at the back of the flat all meant that we survived.
