Greg is a very welcoming, intelligent and nice person, who would take his time to introduce the area to you. Also the apartment is pretty beautiful. Unfortunately Greg had a renovation in his bathroom/toilet on one day of my stay. There was also a huge renovation in the neighbours' appartment all the time. In such case I'd recommend to inform the guest upfront. Also a little bit weird was the fact to offer the towel of the previous guest because the new one wasn't washed yet. Hmm, maybe this was a misunderstanding. Anyways, afterwards I was sad that I didn't book a hostel or hotel instead.
Greg is mentioning this in the rules, I wasn't paying that much attention, my fault: be aware - it is a non plus ultra smokers apartment!
