Overall, the apartment is well-situated and offers a comfortable habitation. The communication and organization with Wayne was genuinely smooth and flexible throughout the trip and he and his wife are very likeable. :)
Single point to critizise is the shared bathroom which was from our point of view with 4qm a bit too small considering that 2 AirBnb rooms (with usually 2 guests per each) make use of it... hence, it was not really clean. Whoever has a favor for cleanness, and depending on the behavior of the guests, could find it disgusting over the time.
