We booked a 6-bedder in the hostel.
1. The location was fantastic. Right in Edinburgh old town. It was less than 10min away from train station, if you climb a flight of around 30 steps. But if you have a heavy suitcase, you will need to do a detour and that will take you closer to 20min.
2. Description says shared bathroom, but the shared bathroom was actually shared among the whole floor, not in the room. So we felt we were kind of misled.
3. The room (insect) given to us smelled of pee. It was quite strong.
4. It was one of the more affordable accommodations for that location.
If you are looking for a cheap accommodation with a good location, go for it. If you need your comforts, clean and nice smelling rooms, then forget about it
