We stayed here for 7 nights. The studio was a 10 minute walk from the Vatican. Great little secure place. The television had 2 English news channels and the internet connection was good. Nice kitchen although the dishes & pots etc were so off dated and old. The kettle was blocked and dangerous to use. 2 faded plastic perished wine glasses I would not expect the host would even use. There was only one toilet roll and no washing up liquid. We left 3 toilet rolls, 2 kitchen rolls and washing up liquid that cost very little.
The shower water spray head was so poor and obviously broken. The bed was comfortable but the wood corners we kept hurting our legs on as you walk past.
There is a late arrival fee of €20 after 10pm and €30 after midnight.
I mean this as constructive criticism and hopefully the host will have taken this into consideration and made changes by the time you book your stay.
