Igor's place is perfectly located to see all that Edinburgh to offer. I walked everywhere but there is also a tram stop right outside the main door to the flat. The room is huge and very comfortable and brightly decorated. Igor himself is full of suggestions for places to eat and things to see in the city, and treated me like an old friend immediately. I would definitely recommend staying with Igor if you don't know anyone in Edinburgh (or even if you do). The only caveat would be if you can't handle four flights of stairs every day, you may want to stay elsewhere.
