What a brilliant place to stay! The whole house has been very well decorated to feel modern and comfortable and had everything we needed. You couldn't be closer to the fortress itself and are just a short walk from the modern town and the Canal du Midi (we spent a great day hiring bikes!). Having private parking is a huge bonus too and there is plenty to explore nearby, so I would recommend hiring a car for your holiday.
Before we visited, we were worried about being on the main road and next to the car park, but actually this wasn't a problem at all. You feel comfortable in the front garden eating/relaxing and the back garden is nice and quiet too.
It was a really hot couple of weeks when we visited, but fans are provided for all of the rooms (and these were definitely needed!). There obviously is no pool, but we enjoyed swimming in the nearby lake (about a 10 minute drive away) on a couple of days.
Thanks to Cathy and also Maria who made us feel really welcome and was helpful on our arrival.
If you are looking for a place to explore Carcassonne and the surrounding area, this is the one!
