Unfortunately I could not meet the owner personally as he was on vacation at the time I visited but the communication was always very cordial. Instead I was given a contact of a 3rd person to deal with and he was pretty attentive even when he had to wait for me quite a while as the plans of the trip from Stuttgart to Nice did not happened exactly as planned due to traffic and some other issues that I have warned the owner previously to my trip. My overall experience of the apartment deal was very good and I would book it again in the future.
Very welcoming and generous (wine, food)
always answered his cel. phone
was at the train station to walk us to the apartment
lots of tourist info from host
