Amazing stay, very close to Termini and Hop-on sightseeing bus stop. Various shops around for food and drinks, if you are not very perticular about it. Sparkling clean place, great for 3 but difficult for 4, felt very cramped with 2+2kids. You may be sharing same floor with others as there are multiple doors on the same floor. You will have your own separate bathroom, without washing machine.
Common Breakfast area is on another floor which had some great breakfast items to start your day. Overall worked well for me, except for packing and unpacking time.
When we arrived, there was a staff who helped us check-in and shared map etc. Nevertheless, instructions were very clear that even if he wasn't there, we could have managed self check-in. Not sure why folks who came in the evening were puzzled.
Over all great place for 3.
