Gabriel place is very clean and nicely located.
It is just less than 10 minutes walk away from Vatican City. This is very important point, as coming to Vatican in the early hours would allow you make nice photograph with no-crowd. And accessing the St Peter's Basilica church is very convenient with no queue in the early hours.
Going to the Rome city's attraction places is very quick with bus in 10-15 mins only. It is very convenient.
Finding parking around is also easy when renting car, and parking charges is very cheap overnight. Gabriel provides a clear guidance of where the car can be parked.
It was very easy to find nice restaurant around with very affordable price.
There are also carefour supermarket nearby where you can buy groceries for cooking, in case you are looking to save money for family's dinner after spending breakfast/lunch outside whole day. All the cooking equipment, spices, and oil are provided completely. Laundry machine with detergent and softener are all provided as well.
It feels very convenient and homey.
Gabriel himself is very responsive and accommodative to answer all the queries you may have during your stay in Rome.
Very recommended place to stay. I would come back for my future visit to Rome.
