We came in Porto in November, so it was rainy outside and we enjoyed even more this apartment - we literally didn't want to leave, because it is so cosy, clean and with an amazing view.
It's very comfortable also that you can have a very good breakfast and lunch in the cafe on the ground floor.
The only thing might be not very comfortable - there is not a double, but two single beds. Maybe with an additional mattress it might be more suitable for couples.
Anyway, we enjoyed our stay a lot.
