It was probably even my fault, so we did not communicate sooner. I texted soon in the morning(sms/whatsapp/airbnb) to store my luggage in the flat and the reply came after 4 hours, so we had to use quite expensive luggage storage 100m away from the flat.
I received some self-service info about keys and room, but not about a flat number. So when we arrive in the evening, host was unreachable on SMS/airbnb again, so I had to try few doors with the key to find the right one.
The rest was fine - room, flat, bathroom is in good condition and we like that. We had to leave at 4 AM to catch the flight - buses are very close, so the position is good, if you have flight soon in the morning. So, mixed feelings, but someone more choleric would be very upset I guess.
