Derek is a GREAT host, very kindly, he gave us many tips about the area and Edinburgh in general.
He helped us at our arrival to get all buggage to the apartment.
We are a family of 4 (with 2 children) and Dereks' apartment had everything we needed (including toys for kids). Very clean.
The location is ok, quite zone, with food places at 5 minuts walking, and playgrounds very close. Lots of public transport (bus) combinations to reach the center in 20 minuts
