i stayed for 6 weeks. Kunal gave me a really good price for the long term stay. The bed is really comfortable. haven't tried the bed/couch for sleeping. The living/kitchen room is very cozy and comfortable. the place has really good bus connections. there is a bus stop right infront of the building's door, i mainly used it on the way back from old town or city center using bus 7 or 14 that goes through old town and stops at north bridge as well. otherwise i used another bus stop which is 2 minutes walking from the building, you can take bus 7/14/34/10 into city center and onwards, a lot of variety of buses to be honest which is great. Mainly the journey would take 20 to 30 minutes from to city center. i have taken a taxi from princess street to the flat a few times for around 7 to 9 pounds, which is great especially if you are splitting the ride with someone else.
there is a tesco 5 minutes away and a scotmid supermarket i think 3 minutes away.
there is a great small polish cafe infront of the flat thats open until 3pm and serves breakfast coffee some sandwiches and snacks that i have used quiet often. finally there is a river passing by on the back of the building which is great for morning walks. i recommend!
