It is a lovely flat in a great location. However, there are a few things which aren't quite right about it and which could easily be put right by the owners.
1. There is no hanging or shelve space in the bedroom. Nor a chair to throw things onto. If you don't mind living out of a suitcase, fine. But if you are staying more than a few days it may well get a little annoying.
2. There are no coat hanging space in the hallway either - easy to fix. The only hanging is in the TV area/snug where the sofa bed is (which we used as a bedroom).
3. The bathroom is small. Again, a little more thought as to how to fit it out would make it perfect. How about a few shelves to stack some toiletries? A soap holder/shelf in the shower cubicle itself?
4. No dishwasher.
5. Bedroom is in the loft - I think it will get very hot in the summer (we were there in June - it was ok).
That all said, the flat had charm. Overlooks St Giles Cathedral. Very centrally located. (Might get noisy when tourism is back at full throttle.)
