This is a magnificent large apartment in a handsome Georgian terrace. Perfectly placed for exploring all parts of the city, including old and new towns, the parliament building and Arthur's seat, and the Royal Mile leading to the castle. The botanical gardens are about 20 mins away on foot and definitely worth a visit. We were in Edinburgh for the Fringe and all venues we visited were between 20 and 35 mins leisurely walk away. There are enough pubs, coffee shops and restaurants in the immediate vicinity to keep anyone happy for days. Even an organic super market just round the corner. Tesco metro is just up the hill.
The apartment is up one short flight of stairs. It's quiet and peaceful. The beds are large and extremely comfortable. Be aware there is only one bathroom (and the toilet is in it). Not a problem for us 4, but might be an issue if all beds are full and your party includes teens (or anyone else) who likes to soak in the bath. This minor inconvenience is worth it for a few nights in a beautiful historic apartment in a beautiful historic city.
