Great location. Really close to the attractions we'd booked with our two children. Dungeons, Camera Obscura, National Museum and the Ghost Tour even set off from right across the road!
The flat itself would benefit from redecoration but this did not impact on our stay at all. We just needed somewhere cosy and clean to sleep for a couple of nights and a place to run back to in the rain! The four flights of stairs did not matter at all - Edinburgh Old Town itself has lots of stairs and we're all capable of getting up them.
We would stay here again. Thank you.
