Robert's place was literally perfect. I'm a girl, I spent 3 nights of my vacation alone in his place, and I was feeling totally safe for during the whole stay. I really appreciated it.
The place was absolutely clean and well organized. The kitchen and living room (also works as a perfect dining room for a couple) were spacious. If you take advantage of kitchens of airbnbs, you know that it's general to encounter oily stoves. However, the stove and pans, and everything in his place were incredibly clean, which was amazing.
2-4 lines of buses come to the bus stop for every 5-10 mins, which is right in front of the apartment. Location is so great, unless you want to stay in the very center of Edinburgh. The daily tickets for the buses in the city cost 4 pounds, and 1.6 pounds for a single ticket. So it's not a big deal.
I highly recommend this place. I'd definitely love to visit his place if I come to this lovely city, Edinburgh.
