My friend and I arrived very late (after 12am) but luckily that was no problem. Alejandro was very kind and welcoming and explained us everything. We met Harriet in the morning, she's also very nice and helpful. If you have any questions or want information about what to do in Edinburgh, Don't hesitate to ask them.
The room was very clean, had its own bathroom and the bed was very comfortable.
We enjoyed our stay and we'd definitely recommend this accomodation.
