Everybody seemed to have had a good experience except us. A few days before our trip, I communicated to Ruslana the checkin time (sometime between 6pm and 9 pm). She messaged us with the wi fi password and told us to connect outside the house and phone her when we arrive.
Day of the trip: after driving 10 hours, we reach Ruslana's place at around 7pm. Called her mobile phone and whatsapp call several times with no response.
Imagine how difficult it is to find a new booking late at night with only 5% of the listing being available that day in Thessaloniki.
We still don't know what happened.
