Stone house in the old town with potential to convert into a b&b, hostel or similar

The property is located just a stone throw from the main market square in Vodnjan. The town used to be the administrative centre during the Roman times for the Istria region. Today Vodnjan is like a "living museum" with authentic Istrian stone town houses. Pula, the capitol of Istria, as well as the sea near the fishing town of Fažana, are both just a 10 minute drive away.
This is an ideal location to open a hostel or b&b. Neither exist so far in Vodnjan.
The property consists of 3 adjacent stone houses. There is a total surface area of 122 sq m. The main building has 4 floors, the other 2 buildings can have a total of 2 floors each (currently gruond floors only). Hence the property can offer around 220 sq m of living area plus a small garden.
There has already been a plan to convert the buildings intoa hostel. The entrance was going to be in the property located in the middle with bedrooms and bathrooms on the upper floors and a reception etc. on the ground floor.
The building is in good condition and has town water and electricity.
