Dear eva6sus, thank you for asking!
We do provide set of towels and complimentary toiletries in all rooms. For law restrictions, we cannot provide an iron for our guests' use, but we may suggest you some laundry services close to our guesthouse or if you wish so, take care of your laundry, just ask our reception for further help.
In Italy an Euro adapter is vital ;)
Hope this may help!
Best regards from Merulana Inn
