We spent four nights in João's penthouse apartment and really enjoyed it. It is large, modern and very spacious. Loved the fact that it had two separate bathrooms, each with a shower. The living room was really cosy, and the heating worked well. It was also really convenient to find a place in central Porto with private, secure, off-street parking, although the entrance to the car park is extremely tight: don't go turning up with a large rental vehicle or you will really struggle to get in there! I had a Peugeot 208 (not a big car) and still almost scratched the front bumper trying to get in. However, once you are in the car park it is very spacious. We were walking distance from lots of the main sights including the riverfront, and just around the corner from one of the best restaurants in the city (Cúmplice Steakhouse). Overall, we had a great time and would definitely stay here again!
