I went to Edinburgh with my girlfriend's family. In total there was 7 of us, including one child, but the house felt in no way cramped. Rona's place was perfect for families/large groups of people. The house had everything we needed and more, was incredibly comfortable.
It is perfectly situated with regards to the city, which is a very walkable distance away. It also has plenty of public transport links that make it very easy to get too and from the centre.
Rona provided me with plenty of information about transport and things to do, which was very useful.
I would definitely recommend her place with hesitation, and rate it 5/5.
