We very much enjoyed our stay in Edinburgh. The apartment was clean, comfortable and well-furnished. Several reviews had mentioned problems with the blinds or plumbing; we found everything to be in perfect working order. The kitchen was convenient and well-stocked (mugs, wine glasses, anything we needed). The shower worked great and the bathtub was large and comfortable. Beds were fine to sleep on, and after a week in London, we really appreciated the quiet. For folks who can walk well, it's a quick walk up the street to many convenient bus stops.
Some extra information for guests with mobility challenges: this property was listed as suitable for guests in wheelchairs. If you use a folding/collapsable wheelchair while out and about but are mobile in the home and able to climb a tall stair or climb in and out of a bathtub, this is a great apartment for you. It has an elevator to get from the ground floor to the second floor apartment. However, there is a curb-height stair into the building (which also has a door threshold on it, so in practice it's difficult to ascend in a manual wheelchair). Also, the doors inside the apartment are too narrow to accommodate a standard manual wheelchair. We needed to remove the wheels from my (rigid frame/non-folding) wheelchair to get it through the wider exterior door, and it did not fit through any interior doorways in the apartment. There are no grab bars in the bathrooms, and the shower requires about a 1 foot (30 cm) step to get in or out. Because I was traveling with adult family members, we were able to manage and enjoy the lovely apartment, but if I were on my own or only with my children, we would not have been able to stay.
Also, the apartment is down a fairly steep, cobblestone hill. No problem if you can walk well, but challenging to ascend or descend in a manual wheelchair. We took a lot of taxis, so we were fine, but if you planned to make much use of the bus system, this is not a good choice for a wheelchair user.
