Very Spacious! We had 9 people and it didn’t feel cramped at all. We loved the high ceilings and the views from all the rooms. Amazing location! You are about two streets down from the Royal Mile, so you are truly in the heart of Old Town. Everything we did was walkable!
The only difficulty with the flat was the toilet. There was only one bathroom which can be difficult for a big group, and the toilet took a while to flush. Sometimes we had to wait a few minutes between each person who used it for it to actually flush. Also, one morning we got woken up by someone pounding on the front door, which was frightening. We read the other reviews and someone had stated the downstairs neighbor will knock and play loud music early in the morning because they don’t like people making noise above them. We felt safe because even the individual bedroom doors lock, but I wish we had been warned beforehand because it was scary to wake up to.
However, overall we loved this place!
