The location and view are worth the 4 (5?) flights up. Then again, most of Edinburgh is hills and stairs, so this is par for the course. We loved the added details and nice touches in the apartment (honesty bar, city guide, a little shop of goodies by the window!). The location is right by a busy area so expect some light sounds here and there, but nothing that lasts more than 10 seconds. The area is vacated pretty early at night and you will have no problem sleeping (especially with the blackout shade in the bedroom). Also, the hosts were very quick with communications and very helpful with recommendations. I would definitely come back. Thanks for the great place to stay!
