William's place is lovely. I never met William but he was very helpful with my check in over messaging as I (ridiculously) got a bit lost on my way in!
I did meet Peter, who was very friendly, and we had some great chats in the kitchen. He also offered me some tips on where to go and what to see, which I really appreciated.
The room was quite big and there's a lovely large window, as well as a desk where William has left a bunch of brochures and info about Edinburgh and tours etc. To me, having a private bathroom inside the room was incredible - especially given the price per night. The bed was cosy, and there were extra blankets if I needed them (I didn't - the heating worked perfectly). The apartment itself is beautifully decorated, and the kitchen is clean and sunny (when there is sun!).
The apartment is very close to buses, and given how compact Edinburgh is, it's only a 25 minute walk to Princes Street (you stay on one street basically the whole time!). When I arrived at Waverley Train Station, it was a quick 6 stop bus ride to the apartment, and on the way out, I took a bus back to Waverley and picked up the airport shuttle bus that runs 24 hours a day, so getting around was a breeze.
Overall, I thoroughly enjoyed my stay at William's place and wouldn't hesitate to stay here again next time I visit.
