Exceptional host!
A bit daunting when confronted by pages and pages of must and must-nots prior to arrival. Upon arrival, it was so obvious that all those were needed as the premises is part of an upmarket neighbourhood, part of Justin's home (he lives upstairs but totally separate) and no doubt, one of his prized creations as an architect.
Queries before arrival were promptly answered and communication during the stay unbroken.
Worth pointing out was his pride in hosting his guests and of his home, Justin really went out of his way to ensure our stay was within our expectations and more.
P.S.
The layout might not be suitable for everybody but it suited us to the dot as our daughter's adjoining room was just a door away and all of us could use the toilet and/or bathroom without disturbing the others.
