The hotel was so nice and in a good location, because it's right in front of Holyrood Abbey, the palace and Arthur's Seat. Also it is very quiet but not too far from the center!
The service was so nice and kind, always up to help. Also it is a plus that the reception is 24h for people that arrives with flights late at night.
If I had to say something with that I wasn't comfortable at all ( Compared with some other hotels around UK or Europe) was with that you have to pay for towels, soap and some facilities that by the normal there are inside of all the rooms in current hotels. But this wasn't bad at all, because as I said, when you are young and a traveller, that things aren't bad at all. Just because we are young and we do not care so much about it. And the only thing with I was absolutely uncomfortable (Literally) was with the bed. I had back pain for days because it was really uncomfortable, maybe old mattress and springs nailed to my back... The floor was more comfortable.
But! Despite that, I would went again! There are more in favour than against.
