Lovely house and great place. Requires a bit of walking if you like walking, but very close to a Metro stop if not. I would say only two things:
1. The en suite is not exactly private (to the other guests); this means travelling with people you do not know so well (e.g work) or something could become embarrassing quite quickly.
2. It is more of a 'hotel style' than 'Couchsurfing style'. Communication was great and they were super flexible, but if you would also like a host that you can share stuff with it might not be best.
These are not criticisms; we had a great time and I highly recommend it, but just so others know what they are getting.
