Really fantastic spot to hang out in Edinburgh. Not just close to everything, but right in the middle of everything!! Nice layout in the apartment with excellent amenities. The views over Edinburgh are top notch.
As noted, there are many stairs to get up to the apartment - pack lightly and be prepared for the climb. Once you are up, it is well worth it. The floors in the apartment are wood and do make for creaky noises when walking on them, so if you have room mates sharing the place, just take note that you will hear them throughout the place.
A really nice place and enjoyable stay. Steven is outstanding with communication and with tips and things to do in Edinburgh. Highly recommended.
