We stayed for 2 nights at Bryony's place over Edinburgh marathon weekend.
1) Check-in was very easy and convenient. We were welcomed by Frank who showed us around the apartment.
2) The bedroom is quite small with double bed and a working desk. The bedroom has no door lock though.
3) As for bathroom, towels, soap, shampoo were provided.
4) location is 1 min walk from Tesco and other awesome restaurant.
As listed in the post, you can't use kitchen and living room, so if you are looking for just a place to take a shower and sleep in a great and quiet location. Look no further!
