We really enjoyed our stay in Edinburgh in the flat. Derek made the flat extra welcoming and cosy with many nice little touches: there was muffin waiting for us when we arrive, maps on the table, international power adapters etc.
Derek was very helpful and prompt with any queries we have.

Though the flat is slightly away from old-town centre (half an hour walk), it was close to bus station, about 15 minute ride a way from Waverly station.
