We had a lovely 6-night stay at Rosemarie's apartment. The location couldn't be better: 2-3 minute walk from the station and very short walking distance to the city centre, Princes St, Edinburgh Castle, etc. It is just by Calton Hill and has excellent views (you can see Hume's tomb from the kitchen!). The garden is fantastic, although the weather didn't let us enjoy it as much as we would have liked.
Rosemarie sent clear instructions before arrival on how to check in and was in contact with us during the stay. Everything was very clean when we arrived and looked just like in the pictures. The house is fully equipped, we could cook breakfast and dinner at home every day, do laundry, etc. The bed was really really comfortable.
Great stay! I thoroughly recommend to anyone.
