This place is just amazing - the location in in-front of the train station and just a little bit far away from the centre, which offers you to feel locals - their food, vibe...
The check in was easy, bed is extra comfortable, the bathroom was extra clean. The kitchen is well equiped. We only had breakfast and light dinner in the place, but could do a proper lunch or dinner.
The host was extra fast with communication, we had few little issues during one stay, but they resolved them in no time!
If you want to explore and feel Porto, you should stay in this charming little clean apartment.
