We had an incredible stay at Peter's flat. Very close to Edinburgh's city centre, easy access to various bus routes, and more importantly the flat is very cozy and beds are very comfy. Lots of storage place for long stay. We even fully utilised the kitchen.
Just one thing to highlight is regarding the lockbox. We arrived late at night (international flight), without having access to UK sim yet. And we spent almost 30 minutes in freezing Edinburgh weather looking for the lockbox. I would recommend that the description of the location be improved.
Thanks Peter!
