We enjoyed our time in this nice appartment. It is very close to the old town and you can reach everything by foot easily. It is located in a quiet neighbourhood, which is rare since the streets in porto tend to be quite loudly due to the cobbelstone on the streets. However, the walls are badly soundproofed so we sometimes woke up to noise of construction works etc. Check in and communications worked just fine. The appartment was clean and pretty. All in all we would recommend to stay here.
