Communication with Vitali was very smooth and timely. He helps you with literally everything you need and answers all your questions. As for the location, there is a supermarket and food right around the corner. The metro to the duomo is a 5 min walk and about a 10-15 minute subway ride. The house itself is very modern and has all the amenities a traveler would need. We were a group of 5 and we all fit very comfortable. Definitely a steal for the price.
