While the flat is in a great location for tourism, there is a ton of construction work outside which can wake you up early in the morning.
Overall, the flat was clean and pleasant, however we had to boil water on the hob as the electric kettle is a bit grotesque on the inside beyond normal rusting.
The stairwell leading up to the flat smells of cat piss, incense, and marijuana.
The worst part of this flat was the "king" size bed, which is 2 singles pushed together. They come apart and someone always ends up sleeping partially in the crack between mattresses. Additionally, the sofas in the main living area have lost cushion and are pretty uncomfortable to sit or lay on.
I did enjoy my stay here and was pleased with the ease of access to the Royal Mile, University, and Parliament. These "complaints" are by far not the worst I've experienced, and if you aren't spending the much time in the flat , they don't make much difference.
