Yan is a hospitable and amazing host. His responses are quick and respectful.
The neighborhood is quiet and safe, but most importantly, his place really makes you feel at home. The lighting is bright in all places, the amenities are more than enough and all the furniture is very comfortable. For instance, the portable heater is a nice addition for people who get cold easily, and the washing machine and dryer have been kept very clean and are convenient for those staying a few days.
Personally, I think the place at which you stay at can play a role in making your vacation or visit more memorable or worse, but Yan's place made mine better. Similar to other comments, it's a place worth recommending.
