We stayed at Sevi's place for two nights. Communication prior the visit was outstanding. In the apartment we found a lot of usfull information, including great tips for restaurants in walking distance. Though we haven't meet Sevi in person (self check-in/out), but there were very nice wellcoming touches and surprises.
The location is very good. Just 10 min walk to Dean Village, no more then 30 min walk to the Old Town and you get to see the town without all the tourist (and this is a beautiful town!). Lots of restaurants and stores just around the corner. But very quiet street. Perfect if you come to Edinbrough with kids. And there are lots of games in the apartment and Netflix if you want to spend a day inside.
As a smoker I loved the privat garden where I could smoke. The entrance to it is outside of the building.
