Manuel’s place is clean and in good condition. I didn’t meet Manuel, there was a women who lives in that flat. But I wasn’t at home at all so that need to be taken into account. Location is not as it is written. Metro is not that close from home, and you cannot go to the river by foot by 10minutes (it takes around 1 hour I would say, because it is around 3,4 kilometers).
For that price in Porto place is good. Just need to take into account that location is not as it is in informationa about place.
