This is a brilliantly located flat that made for a fantastic base to explore the city and the festival. We did find it took us more than 15 mins to walk into the centre with our two kids (aged 7 and 10) but the excellent bus service meant it was no problem at all (make sure you download the two Lothian bus apps - for tickets and service details).
The flat was as described. It is located beneath the family home and has its own entrance. Off street parking is really helpful. We found everything we needed in the flat and it is excellently presented throughout and was incredibly clean. Beautifully fresh smelling bedding and fresh flowers makes it especially homely. All the guidebooks were a really helpful resource.
All in all we had a great time and Jane was an excellent host who was really prompt to reply to messages and on hand for advice whenever we needed it. All the little things made it particularly welcoming. We would highly recommend this as a place to stay.
