My wife and I stayed here for two nights on a short trip through the U.K., and our stay was fantastic. The apartment is extravagantly designed, and is right in the middle of everything you'd want to do in Edinburgh. I mean it wasn't more than a twenty minute walk to everything we wanted to see or do. And every though is very central, it wasn't noisy at night or overrun with late night partiers. Parking was also very convenient, just down the street at the Omni Center. Being near the Omni Center is also a plus when asking for directions in case you get lost!
And did I mention the design of this place? Very upscale European decor, which really added to the experience. There's even a jacuzzi tub, which my wife loved. Now it's not a huge place, but plenty of space for two to sleep and maybe unwind in the evenings.
My only complaints are that the bed is not the most comfortable, and that there are three flights of steps to walk up (of course there's nothing to be done about that).
Communication with Lindsey was great. She was very prompt and helpful. Checkin was easy as well. Lindsey even had bread, eggs, coffee, tea, butter, and a few other little items stocked on our arrival. All in all, we had a great stay here, and I wouldn't hesitate to stay again!
