Gisela gave us a very warm welcome and didn't hesitate giving us suggestions on what to do in and around Porto, especially with the Marathon taking part. The apartment has everything you need and is way better than any hotel in my opinion, plus it has a perfect location in the city centre. The interior was more than you could expect - overall I would definitely stay here again!
The only thing that could be criticised may be the noise from the streets in the night, but we had no problems sleeping due to tiredness. Just bring some earplugs in case you are a sensitive sleeper.
