We really enjoyed staying at Sarah's apartment for the week we were there.
Location - It's in a quiet area near the university. Very little street noise and it seemed to be mostly quiet students in the building. The building itself is very cool and quite recognizable which was a nice help when checking in. Across the street is a fabulous burger restaurant with pretty inexpensive beers and cocktails and there's a small grocery store about 500 feet down the street. It's only about a 10 minute walk away from the Royal Mile and other attractions; it was pretty nice getting away from the big tourist areas at the end of the day. Plus there are tons of great restaurants close by, we highly recommend Mum's!
Comfort - We were very happy in the apartment. This was our first time staying in a murphy-type bed and it was so comfortable! We were also quite happy with the layout of the bathroom, very spacious and the shower has a door which fully shuts to seal the water in! (I know that sounds basic, but all the other spots we stayed in on this trip had a sort of half shield door that always, always let water bounce out.) There's a full kitchen in the apartment, plus a washer/dryer and a cool lofted office area.
We struggled with the wifi connection being weak a bit, but that's our only complaint.
Thank you Sarah for the wonderful and comfortable stay! We highly recommend staying here and would absolutely come back again.
