We really enjoyed our stay at this charming place in the dead centre of town.
We had read about stairs but nonetheless were a little surprised at how many there were - both to get to the building (located literally on a long flight of stairs along a passage up from the lower part of town where the train station is/ up to the Old Town) and inside the building to get to the top floor flat. Not a problem for us and our (too much) luggage, but definitely could be a challenge for some. We found the apartment to be quite comfortable: nice sitting area with kitchen; comfortable beds and bathrooms. Jonathan was exceptionally prompt and reliable in replying to any of our messages, even during our arrival when we had a little trouble finding the place (some roads were under construction). We would recommend this as a good place to stay in Edinburgh and you would be hard pressed to find a more central location!
