I stayed at the Barnes B&B number 001 at Merthyr Terrace just off Castelnau. I was only there for one night but it was an absolutely beautiful place. This is a very small hotel with a personal feel, homely yet also private. Wendy and Richard made me extremely welcome and the room I was in was spotless and beautifully appointed. The breakfast is delicious and the surroundings and garden are lovely; there are also fantastic riverside views nearby. I would jump at the chance to stay here again, it really is the very best of what a British B&B can offer.
