I would not book or recommend this accommodation. Whilst in a good location in Monti, it doesn't make for a comfortable stay. There are 4 flights of stairs with no elevator, there are 4 locked doors to get up to the room (which is secure but time consuming to access and much of the stairs are in the dark).
The iron doesn't really work and is logistically difficult to use with such a small ironing board.
The kitchen items are sparse and the couch is rock hard and the cover is very dirty looking, it is not tempting to sit on to relax.
The bathroom is not super convenient if you want to shower, you only have a hand held shower head which is mainly cold water with low pressure, for which you have to sit in the bathtub to use. The toilet flush barely works.
In the bedroom there is only one light bed cover as a doona - it looks quite old and the bed is relatively hard. There isn't much storage for clothes as the hanger is far too high (about 3 meters from ground) and because the windows have to be open and it's a noisy area you don't want to be a light sleeper.
Over all a convenient location but not a comfortable stay, very cheap and tired looking interior which you will not want to relax in, we spent all our time out of the apartment.
Compared to other places we have stayed in Monti and Rome this was not good value for money, we stayed at other places around the same cost that were much nicer, more spacious and better located.
The positive is that Fabrizio's sister who welcomed us for our stay was very friendly and did a good job trying to make up any language barrier.
