To be honest: perfect.
Even if the check-in seems a bit complicated in the beginning, we had no problems to find and enter the apartement. Joāo provided any informationen needed, answered any question and gave us many very good recommendations for the area.
The apartement was one of the cleanest we've every experienced with Airbnb. The interior is beautiful, the bed very comfortable and the balcony just a dream. We spend every evening out there.
A great place we will surely visit again :)
