Rebecca's place is great value for money and an excellent base to explore Edinburgh.
It's close enough to walk to Princes Street from which you can decide to go right to Old Town or left to New Town. There are lovely restaurants to visit in Lothian street nearby. Bread Meats Bread was one of our favourites as well as the Scottish beer brewer pub, Innis & Gunn.
We would recommend bringing earplugs to sleep as the road in front can get a bit noisy, but the apartment's facilities were excellent. We would highly recommend it.
