We had a lovely stay at Hotel Sangallo after booking a very last minute trip. We were given a lovely warm welcome even though we arrived late evening, and shown to our room (10) which was spacious with a little balcony and beautiful views over the valley. Other reviews have said the hotel is dated - and it is a little, but I hate plastic modern boxes (and so not Tuscany!) so for us it added to the charm. Everything was very clean - fresh bedding and towels every day, and everything functioned as it should. We found the bed a little hard, but generally when staying in Italy this is the case and is just personal preference. There was plenty of free parking, and a great breakfast every day showcasing local produce (charcuterie and pecorino di pienza for example), with some delicious home made cakes to accompany the fresh bread, fruit, yoghurts, eggs etc. Fresh coffee from an extensive menu was also on offer. The hotel is ideally situated in S Albino, close to Chianciano and Montepulciano, as a base to visit all the best things Tuscany and beyond have to offer - but you will need a car to do this. We visited Siena, Florence, Maranello, Montepulciano, Rome and Monte Argentario, so definitely got around a bit! The local pizzeria was good too (Tre Specci) and we ate dinner there three times.
I can recommend this hotel for if you are looking for a friendly, traditional, spacious base with charming, helpful hosts for your trip. We had a lovely holiday.
