João has been a very welcoming host: I had a very pleasant and interesting chat with him upon arrival, and not just about the usual suggestions and questions of what to do and where to eat/drink in Porto (which he has plenty of anyway!). Check-in was very easy and smooth, with the possibility to leave luggage in the apartment before the room was ready. Position is pretty central, with almost everything at walking distance. Room is quite essential, but tidy and comfy. Strongly suggested for a typical stay in Porto.
