Marc's place is amazing. Sitting atop a great centralized location in Edinburgh, you will feel right amidst the energy of the city, yet above it all. The windows and giant electronic skylights will provide all of the airflow you need if you're there during the summer. Though, with both of the skylights open, I worried birds would fly in so I didn't keep them open all of the time. haha.
Marc provides simple toiletries, nothing fancy, but adequate. The modern kitchen is very nice, complete with wine cooler and a washer and dryer. I did have a hard time finding light switches and such, I made it a little game.
The bed was comfy. I slept great, yet I was awoken by construction in the morning; they're building a new structure across the street.
The elevator will take you to the 4th floor, but then you will need to carry your luggage up two+ flights of winding stairs which is a good workout if you're on a long trip like I was. (I needed to take two trips) But not many of the old apartment buildings in the area have elevators at all so it was better than most. The other unique feature of this penthouse is the other floors are not residential. Over the weekend, I believe I was the only person going in and out which made me feel like I had the whole building to myself.
Marc was always responsive and very helpful when I had any questions. I feel in love with Edinburgh and can't wait to come back and hopefully stay in Marc's place again!
