Nice and super clean flat with everything you need for your stay (cf. pictures, just the view from the balcony is not as green as it looks on one of the pictures.). Loreta gives lots of helpful information about what to see and to do in Porto. The communication was very pleasant and we felt very welcome.
It could be just a little closer to the historical centre, but then it also might be a bit more expensive and you quickly get used to take the metro, so it's fine.
We enjoyed our stay a lot in the friendly appartment, was a nice starting point for our daily tours!
