The communication with Jonathan was very good. He responds quickly and adequate. The place is located almost perfect. On the one hand it is a nice and quiet neighborhood and on the other hand you only have to walk 5 mins and you find yourself among shops, bars, great architecture, cafés and a vibrant city center atmosphere.
Checking in and out was very easy and the appartement is great. We were to friends having only a couple of days exploring Edinburgh but you can easily stay there longer with kids and family.
I was actually thinking about staying in Leith because I read good things about that area but I can fully recommend this place and we didn't regret our choice at all :) The beautiful Calton Hill is also only a short walk away.
