I feel lucky to have had Jonanthan as a guest. Generous and kind words created a special Christmas time for the busy household. I only wish I could have heard his bass voice. I am sure it was as supreme as was his attitude. Thanks Jonathan for staying with us! You will always be welcomed in our home any time.
Jonathan was the perfect guest, effective and convenient in all communication. We were abroad when he and his friends left the flat and he even bothered to call us to thank for the stay and check if he was leaving the flat as we would like it. We appreciated that a lot. The perfect guest!
Jonathan was a great guest. Very interesting to talk to as he's doing some cutting edge stuff! Welcome back anytime.
I've known Jonathan since business school. He is a lovely human being and would make both a conscientious guest and host. Plus he sings a cappella, so if you're lucky enough to host him, make sure you pressure him to sing for his (paleo) supper. =)
I've known Jonathan for around 6 years. We met at a conference and hit it off immediately. We've been good friends, even though a thousand miles separates us. He's a very, very decent person who is respectful, responsible and has a very innate understanding of how to conduct himself in all settings.
That being said, he's also a helluva lot of fun to travel with and sit at a pub and chat with. Just an all around great guy. AAAAAA+++++++ would befriend again!
Jonathan (Sheffi as his friends and I call him) is one of the nicest, most sincere people I know. He's also incredibly friendly and gregarious and makes great friends no matter where he goes. Heck, if I had a sister I'd let him date her! Yes, he's that great of a guy. Always going to awesome events around town. I'd rent a room to him in a heartbeat.
