My Porto experience was very positive!
It is a very easy going city, I will definately come again (during or not during the Primavera Soundfestival- in Parque de La Ciudad).

The flat is exactly what the description is, very well situated in the city (around 15 min by walk from the Douro river). Very clear, very clean and well decorated (simple but effective). When you re in the bed, you see typical roofs and the sky; when you re at the window you see a beautiful typical church.

The only thing why I did not put 5 but 4 stars is because of the bus stop situated in front of the flat... I know this is very convinient, but could be noisy too.

Anyway, this studio is perfect for one or two persons and so much better than a hotel room!

By the way, the hosts are very nice, and easy to speak with.

Cheers,
B
