Punctual, informative, gracious, responsive, professional and patient.
Getting out of LHR, and then from the airport to Michael's place took longer than expected, do to a few delays. I had a class to teach, and I was in danger of being late.
Michael patiently waited for me after not hearing from me (I had no cell connectivity) and he made a fast check-in possible. Which allowed me to make my class on time.
Michael was extremely responsive and professional - he also provided a wealth of information about the local area and Greater London. I really appreciated Michael as a host.
