This is a spacious apartment in a relatively quiet area, although close to shops and a bus route. It was very clean and tidy, and Eric had left tea, coffee, cereals and milk for us in the kitchen - a nice touch.
Although it is on the top floor the stairs are an easy climb, and we were barely aware of our neighbours. There is a good size double bed in the bedroom, and in the lounge a large sofa bed which is very comfortable. A small but well-equipped kitchen, and a nice shower room.
The area is within walking distance of the centre of the city, but there are also frequent buses, so the shops and attractions are easily accessible.
Eric gave us a long list of things to do in the city, including recommendations for eating out, and took great care to explain collecting the key, what do do with the rubbish, managing the hot water, etc. He also responded very promptly to any questions.
I would happily recommend Eric's apartment for a stay in Edinburgh.
