Our family owns the entire second floor and has decided to dedicate half of the space to welcome guests.
The apartment we rent is around 120 square meters (1300 sq ft) and includes an entrance with marble floor, two bedrooms with their en-suite bathroom, a large reception lounge and a fully equipped kitchen, all decorated with original paintings and furniture from the 16th, 17th and 18th century.
It has just been completely renovated to accommodate air conditioning, a new heating system and large isolating windows. Ceilings have original renaissance paintings. 
Our private terrace of 33 square meters (350 sq ft) overlooking the cupola of the famous Santa Agnese of Piazza Navona is open to our guests.
