We had a nice time staying in Ana's flat in Porto, especially given its location close to the nightlife of the city! Everything was in walking distance as well. The only not so positive thing I want to note is the shower. It is quite small (expected in Europe) but the exposed metal pipes in the shower get scalding hot and when there is not room to move around and you accidentally lean onto them, you wind up with a huge burn on your leg like I did. Otherwise, our stay was nice for our visit to Porto.
