While it is located in a central, convenient location, I would advise checking the street name & exact location carefully, since there are many with a similar name “Montecalvario” and navigating the neighborhood can get quite intricate.
Overall the accommodation was very roomy, modern, clean, and generally well-equipped (with a hair dryer and coffee machine). There is heating and air conditioning too. There was no soap however, and the coffee capsules provided were the wrong type for the coffee machine.
The one big downside, unfortunately, was communication with the hosts, which I found to be overwhelming and frankly annoying during our stay. For this reason, I would not repeat the experience and advise anyone who is looking to book this to be aware. (eg. during our stay they asked us to empty the air conditioner units. I would think HVAC and house maintenance matters should not be expected of guests staying in an accommodation).
I would also add that they charged us 20 euros extra for arriving a little bit late after 7 PM and were not flexible despite commenting that the metro does usually run late and that most people get lost in the street trying to find such a common street name.
