Filomena is a great host, and her apartment is good sized, well cleaned and in a very very central location in Rome.
We've enjoyed our 3 night stay, with our baby, and Filomena was always responsive and helpful when we needed something.
Be aware that the building doesn't have an elevator, but Filomena also mentions this in the listing. It's just a hassle to carry stuff up and down during checking/checkout, but day to day use of the stairs wasn't a big deal. Apartment is 3rd floor.
We recommend her place to anyone visiting Rome and want to be walking distance to all attractions. (nothing is more than 15 minutes walk away)
