The communication was mainly through the messenger on Airbnb site and whatsapp. All required details were provided and the responses were also in time.
There was no contact with the host though as the keys were placed in the mailbox and we also placed the key in the mailbox on our departure.
The required description regarding Wifi and other emergency numbers were provided in the note left in the mailbox. In addition, there was a map of the city and guide of the important locations in the city which was very helpful.
