Alex is the perfect host: he's always available to provide you all the information you need; his responses are faster and he's very helpful (he sent me the better way to reach the house from the airport, even walking for 20 minutes from a certain point, all via Whatsapp).
The apartment is really nice, even better than by real. When I arrived, everything was tidy and clean. I felt a warm welcome as well, thanks to some details very appreciated.
The only negative feedback I have to give is about the lock of the main door: to get in the building it's very hard turn the key. Yu must find out the right way to turn the key and get in easily.
