Hi Tim, first of all thanks for choosing my flat.
I would like to clarify a couple of things : this apartment generally accommodates comfortably up to 8 people, as you can read and guess from the 30 reviews about it
No groups of 8 have ever complained about the flat being small. I wonder how it could be small for a group of 4 like yours. Besides that, I'm sure that you must have seen from the pictures before coming to Rome that 2 bedrooms share a bathroom and yes, there was a bed in a living room indeed but you still had another living room with the kitchenette to be use as such. About the elevator : the workers were there on your first day only, for maintenance purpose and they finished that very day; from the moment they left the lift worked just fine (it's a brand new one).
I hope to see you again here in Rome, all the best to you and your family
