The apartment is very centrally located and was beautifully decorated. The bed was very comfortable, but the pillows were a bit thin and the sheets/blankets provided a bit light for our tastes. The street is noisy at night, but with the earplugs we didn't lose any sleep. We maybe woke up once or twice, but were able to fall back asleep. Nothing out of the ordinary when traveling and staying in new places.
Rafaela & Celio had the place impeccably clean for us after a quick turnaround from previous guests and also generously allowed us to drop our bags off earlier during their clean up time so that we could enjoy Porto (given that we were only there for a short 2 days). Ultimately, I think this place is superb value and a perfect place to stay if you plan on spending most of your time exploring Porto. We were looking forward to enjoying wine on the balcony, but actually didn't even have time because Porto was so enticing!
