We greatly enjoyed our Edinburgh stay in this first floor (second floor for us Americans) flat. It is a 10 minute walk to Waverley Station; the airport tram is even closer at two blocks, and there is a bus stop (Edinburgh buses are safe and the network is extensive) less than a block away.
The flat is clean and spacious, with a huge parlor and a huge kitchen, two bedrooms, and a full bath. There are loads of magazines and pamphlets available describing Edinburgh attractions. As is usually the case in downtown apartments, there is a compact clothes washer but no dryer. There is a ceiling-mounted rack for drying (a relative term, considering the constant humidity in Edinburgh).
There are numerous restaurants nearby. We especially enjoyed breakfast at Cafe Marlayne's on Picardy Place.
Our interactions with Chris and his daughter were thorough and very pleasant. We did not need assistance during our short stay, but appreciated their offer of assistance if needed.
We would certainly consider this property again if available during a future trip to Edinburgh. There were 4 in our party. Considering the cost over three nights, we had more amenities, more room, and at least as comfortable an environment, for less money, than we could have found with 2 hotel rooms similarly located.
