We LOVED Antonia's flat - it is perfect for a weekend (or longer!) away and will definitely be returning. It is in a very quaint but quirky neighbourhood with some lovely shops/cafes'/restaurants right on the door-step yet we were able to walk every where as it in a great position.
The flat has been meticulously renovated and was deliciously warm (weather was shocking on our visit!) and so quiet in the Mews. The only thing we would have changed is to have had a firmer bed but would recommend it to anyone visiting Edinburgh.
