Convenient location but extremely noisy. Would not recommend this place unless you only need 2 of the 3 bedrooms.
Good points: near Royal Mile, large space, nice views, washing machine and dishwasher, seamless checkin
Bad points: the double bedroom facing the close (alley) is extremely loud, with a pub immediately below it and people walking by yelling all night long. The close is a popular cut through from the Royal Mile to the train station, so you also hear suitcases on cobblestones at all hours. We could not sleep at all and had to get a hotel. The carpet in one bedroom is very stained. All the doors squeak when you open them, disturbing anyone who has managed to sleep through the revelers outside.
