I booked the flat for my elderly parents (both over 80) who took my kids (their grandchildren...) to Rome (4 ppl altogether). I chose it because of it's central location and being on the 1st floor, which makes it easy to come & rest in the flat several times a day.
Well, it turned out the location was indeed great, and the rooms were big, but the maintenance leaves a lot to be desired. from plumbing issues, to the lack of cutlery in the kitchen, not enough blankets, problematic TV reception, unpleasant odor in one of the rooms and simply not being really clean...
The owners were responsive, and tried to fix some of the issues, but the overall experience was somewhat disappointing.
Seems that the Apt. is operated by a company that runs about 20 Apts. in the city, and it doesn't get the necessary attention.
