Joana was very helpful as was very flexible for the check-in. She arranged for us a taxi from the airport on the night of our arrival, and waited for us that night.
The loft was very clean, with all kind of commodities, soaps, bathrobes,... anything you would need, it'll be there.
The loft is perfectly located, right in the city center and walking distance to all the major spots in Porto (and nightlife) :)
I highly recommed Joana's loft for your stay in Porto!!
Hope to go back soon!! ;)
