The apartment is nice, cosy and clean, and more spacious than what it looks in the pictures. It is conveniently located to reach the old town walking (around 20-30 mins max by foot) and close to the bus stop to reach farther places (Such as Leith).
The owners were generally quick to reply to my questions.
More care could be given to what is provided in the house (enough towels for all guests; shower gel/shampoo, which are not provided).
