Walter is a great host, very hospitable and organised. Everything was made to make our arrival in Siena easy and pleasant: map, some good tips for our stay and also very good adresses of restaurants. The flat is also charming and have everything you need. It's very well situated and makes each visit possible just by walking a few minutes. The only disadvantage would be both small bathroom and toilets but it was insignificant regarding the pleasure we had to stay in Siena.
