Eric is very wonderful and he replies to your inquiry pretty quickly.
The location is great as you can basically walk to Arthur's seat and you can take bus to Old Town or New Town. Also, Sainsbury's and Poundland is nearby, so you can buy snacks or other stuff when you need one.
The place is pretty clean and comfortable. However remember to turn up the heater and wait for 15mins before taking the shower XD.
Overall, it is a great place for 2-3 people
