The apartment is simple but lovely. It's got everything you need to have a good time in Porto, including a book with lots of recommendations. It's close to the city center (5 to 10 minutes walking) and next to the Trindade Subway station, which is really convenient. Sílvia was super kind and helpful and always quick to answer any questions we had. The apartment is next to a busy road so it can be a bit noisy, but I brought earplugs so that was no big problem. The bed wasn't great, but fine for a few nights.
