We spent 4 weeks at Bryan's place, which is in a brilliant location close to The Meadows and Summerhall, so easy walking distance into the city / Princes St etc. Bryan and Anne were very helpful with check-in and brought clean bedding and towels halfway into our stay.
We were in Edinburgh for the fringe festival so paid a massively inflated rate. There were a few minor things in the flat that weren't so good - e.g. the kitchen lights were broken so we had to use a lamp, and the washing machine stopped working which meant several trips to the local launderette.
I'd totally recommend Bryan's place for a quick visit / weekend in Edinbugh, but if you're staying long some if it's quirks may become more irritating if they don't get fixed!
