We stayed at John's place on our last day in Edinburgh. As we had just one day, we were keen on staying nearer to the city center and John's house in located bang in the center, just 15 minutes walk from Princes street!
The house is huge and well decorated .It has the old time charm for people who like it. We had reached earlier than the check in time and left our luggage at the house to return later for check in .
The house itself is beautiful but there were areas like kitchen cupboards ( hard to use as they seemed broken), dining table (which wobbles) which could be better- given that its a old house, these things can be overlooked. However, there were no basic amenities like milk, bread, kitchen tissues, smaller utensils etc which would have helped. We also found the house to be a bit dusty when compared to other places we had stayed. However, since we were out most of the time, that did not matter much.
I would suggest this house for any large groups as there is lot of space for everyone.
