It's not just a B&B, providing studios with kitchen and private bathroom, ideal for two people.
I spent a nice weekend in this B&B (that is located close to San Marco), with just 100 Euros per studio per night.

Mike... how difficult was it to reach the B&B? Also, what floor is studio 5 on? Is there a lift? How far in advance did you book? Are the double beds convertable to two twins?
Is this your business?
