Jonathan's flat is close to relatively close to central Edinburgh with lots of buses that one can catch to get into the main Edinburgh Waverley train station (about 15-20 minutes bus ride) or just under an hour's walk. The airport was less than 15 minutes away by uber.
The flat is spacious and was well stocked with amenities (no fear of running out of toilet paper). The WiFi worked well and the TV had a NowTV box which kept us entertained for a early night in. The sofa bed was firm while the main bed was a bit soft for me, but you have a choice if you wanted one or the other.
All in all, it was a pleasant stay.
