Can anyone suggest somewhere I can hole up in central Edinburgh for a couple of hours next week to do some work in the day time? I'm not looking for a paid place just a corner in a cafe or accessible space somewhere (library?), preferably fairly quiet, where they wont mind me getting a laptop out and doing a bit of work. Happy to buy a coffee or coffees there if needed. Ideally somewhere between York Place and Grassmarket area. Ideas please.
