Gavin's place is a nice little flat located very close to the Grassmarket and to the main attractions in Old Edinburgh. It was a great jumping off point for our explorations, and we really enjoyed our time.
Everything was as described and the communication was prompt. Gavin was very helpful.
I would just note that getting to the Wee Coo flat requires climbing up a few slights of steps, which can be tricky with a pram (although we managed just fine). Gavin's got another flat (the Wee Thistle) that is more accessible for those who need it. As I say, though, everything was as described! The Wee Coo does come with a travel cot, which was really handy.
