Great stay at Martin’s place. Location was excellent and very close to Grassmarket, the castle, a grocery store, and shops. Martin even had some groceries waiting for us in the fridge which was so kind and helpful. He met us at the flat to check us in, familiarized us with the apartment, and also suggested some places to see in town. We did have one incident with the lock not opening which left us locked inside, but Martin answered our messages/calls and came to let us out; he said that had never happened before and he would have a locksmith take a look. Overall, a lovely stay and the location can’t be beat!
