Sienna

Martin,
See http://www.slowtrav.com/italy/vr/list.asp?r=Tuscany Siena

Also, try vrbo.com.

In Europe we generally use VRBO.com and Homelidays.com for our apt rentals. Make sure the place you are considering is "established", and has many customer reviews. We also have had good luck going to the local town web site, and finding apts. there.

Don't forget that the 2nd floor is actually the third, and that many places do not have elevators.

When you are picking a place get the address, go to Google maps, and turn on the Street View. Make sure that the place you rent is not on a noisy main street!

Excellent advice about checking to see if it's on a noisy street. We stayed in Siena a few years ago at an RS recommended place - Casa Laura. We decided it should have been called Casa Loud. Our bedroom window opened out onto a major intersection in the historic center. We had no air conditioning but couldn't open our windows at night because of the noise.

Would you be interested in an Agriturismo that is 10 min from the city walls in Siena? We had an absolutely incredible stay at the Agrit. Marciano. The rates were good & the experience was wonderful. My husband and I agreed that our stay there was the highlight of our recent trip to Italy. It's a working organic farm; they produce wine & olive oil. Breakfast is included in the rate & is served around the farmhouse table; it's a nice opportunity to meet other guests from all over the world. They offer dinner a few nights a week and the food was to die for. Everything is fresh & they pair their own wines with each course. It was a great experience & I thought I'd suggest it in case it's something you might be interested in. Have a great trip.
