I did not have cellular service when I landed in Paris however, I was able to get out one message to Oli about being at his place at a certain time. We arrived and after trying to message him to no avail for a minute or two (due to my own cellular service) Oli came outside and met us! That was awesome and really stood out to me. He let us in and was very friendly letting us know about the space. This was a worthwhile stay between flights.
