A group of friends and I booked Jonathan's apartment in Edinburgh for the fringe festival in August. The apartment is exactly as described with 4 good sized double rooms and two bathrooms as well as the kitchen and living room. This was perfect for our group and would be for a family too.
The location is brilliant, 10 mins to Waverley station and the city centre, everything walkable. There are shops, restaurants and bars all within a stones throw but it is not noisy as it is the top floor.

Jonathan is a great host, he responded quickly to my questions, met me at the apartment to show me around and provided tips on the local area.
All in all we thoroughly enjoyed our stay and would definitely stay at this apartment again if back in Edinburgh.
