I stayed in Prayas' apartment with 3 adults. Prayas' apartment was accurately described. The rooms were fair sized and enough for 2 people for each bedroom.
Prayas was very accommodating in the check-in and it was very easy with the door combination. Prayas was VERY prompt with any questions I had regarding restaurants or directions.
The apartment's best feature is the location. It is SO CENTRAL. Royal mile is literally 20 steps from the apartment. 10 minutes walk in each direction to get to all major attractions (Castle, Arthurs Seat). And only 5 minutes walk to the Waverely train station for easy commute when you're arriving or leaving from Edinburgh!
Would definitely recommend to friends and would stay there again!
