Robin's flat is nicely decorated, with a really good sized living room. The bedroom and bathroom are quite small, but were fine for me by myself. The location is excellent, very handy for Nicolson Street and the university and about 15 minutes walk from Princes Street and has bus stops nearby if you don't want to walk. There are lots of good pubs and restaurants nearby, but its not noisy at night so pretty much the perfect balance.
The mortise lock on the flat door wasn't working, and I was slightly nervous leaving my electronics behind just the front door to the block and an old Yale lock. Robin told me that he would be getting this fixed, and hopefully that will be done shortly.
