The flat is indeed in a beautiful and perfect location, walking distance to most of what Edinburgh has to offer. Flat has plenty of space for a big group or family. However, there is no dedicated sitting room. Kitchen well stocked and comfortable beds.
We had hiccups at check-in as keys left in lock box did not open main building door and we had to ring another tenant to let us in who was frustrated as he commented this was not the first time he had to help out. If not for the other tenant kindly helping us not sure how we would have entered the flat. Due to miscommunication we also had the check out cleaning man arrive the day before check out thinking we were meant to be leaving.
One area of suggested improvement would be the bathroom hygiene. During our stay there was quite an overpowering smell from the toilets. The flat has plenty of bathrooms but those seeking good water pressure might need a bit more time.
