Great place in a great Edinburgh location. It's clean and tidy and looks like the photos. t's a big flat filled with natural light. It has a nice open plan kitchen, dining and living space. Nice bathroom with a good shower too. We felt comfortable here and we enjoyed cooking in the kitchen, eating at the table, relaxing on the sofa.
We stayed during the Edinburgh festival, so this place was quite expensive. It lacked some premium touches like good quality toiletries and some kitchen essentials (cooking oil, real coffee, kitchen roll). The bed and pillows won't be to everyone's comfort either. And be aware the bedroom isn't in a proper room, so if you're sharing with someone, noise carries from the kitchen and living spaces across the partition walls.
But overall we had a very enjoyable stay, and I'm sure you will too.
