Booking this accommodation will give you an excellent location from which to explore Edinburgh. You've got supermarkets less than 5 minutes away, it's a casual 10 minute stroll from Waverley, less from the bus station and is surrounded by bars and restaurants without the noise causing any issues.
The apartment itself is brilliantly laid out, is massive and has a bathroom to go with each of the 3 bedrooms so there's plenty of space for 6 people to stay there and not be tripping over each other.
