Great flat in great location with great host.
Exactly as David describes it, the flat is ideally located on the grassmarket within walking distance of everything you could need. It really does have a castle view from the bedroom window which is amazing. The code entry pad is very useful as well once you get used to leaving a flat without the keys!
David was very helpful, replying very promptly and accommodating us for a late departure. He had left food and drink out if we wanted to use it as well and plenty of recommendations in the welcome pack of places to go. Thanks for a great weekend.
