Jens and his roommate were both very nice in all communications. However, because his roommate checked us in, he didn't have access to the AirBnB app, which was the only way we were relying on communicating via wifi since data charges overseas are incredibly expensive for us. We had some late changes to our arrival (still within check-in time) that we relayed to Jens but couldn't get in contact with the roommate. We had to search for wifi and still couldn't get in touch until we turned on data roaming and called. Didn't get in until 1.5 hours later. Everything else about the visit was wonderful, they were incredibly accommodating and the room was comfortable and clean with a fan, waters, and even small chocolates for us! Great location too, close to the river with lots of great food options, and close to public transport. I just think that whoever is in charge of checking in should be able to communicate directly through AirBnB.
