We stayed 4 days with 3 people in Jen's flat.
It is a very nice and clean two bedroom apartment near the Meadows, i.e. in walkable distance to anything worth seeing in Edinburgh (e.g. 20min walk to the castle, and anywhere else).
Jen is a very friendly and accommodating host.
The apartment had everything you need and more (e.g. adapters for electrical devices if not from the UK). Very well equipped kitchen, including tea, coffee, cereals, so that a quick shipping at the nearby supermarket was enough to get stocked for breakfast.
The apartment is well kept and nicely decorated and we felt very much at home and cosy.
Warmly recommended for a few days or longer stay in Edinburgh.
