Jan is truly a superhost. We had a warm and great welcome by Jan and Alan, who explained us everything about the apartment and neighborhood. Apartment was clean, spacious and pictures don't do real justice to the ambience & environment. Other than normal routine stuff (TV), they have something extra for everyone (like Chess for playing, books for reading, etc.) Supermarkets are also nearby and the city centre as well as places for excursion are well connected by public transport (including taxis) which was not expensive either.
All in all, after our bad Airbnb experience in London, experience at Edinburgh with Jan and Alan was truly a healing one, more imperatively for my parents, who simply had advised me to always look for hotels from a future standpoint.
