Apartment location is a "killer feature". It makes every point of attraction easy to get even for a walk. Colosseum is about 5 minutes to reach. Metro station allows to get easily to Villa Borghese, Vatican and main railway station - Termini.
24 hours Carrefour supermarket is also near by.
We were travelling with 1,3 yo baby and had no problems with any points of interest in the city.
Apartment is quite stylish - modern things inside old house. Like lightings, furniture, air condition, electric window shutters etc.
Kitchen is large and can be used as a main room - big table, TV, chairs and door to balcony. There's no electric kettle on the kitchen. I understand that gas cooktop makes a boiling water fast but for a night baby feeding it was a bit of a headache.
Balcony has a nice street view and enough place to relax with evening wine or morning coffee.
Antonietta have kindly provided a playground carpet for the kid.
Car and motorcycle traffic runs almost whole night but it wasn't disturbing. Window shutters helped.
Some reviewers mention a mould smell in one of two bathrooms. That's true
but not annoying. I personally think that old houses in ancient cities like
Rome couldn't be compared to modern hotels. Besides no problems with hot
water or sewers.
Last thing to mention for winter tourists with babies - central city
heating turns off every night. Two electric condition/heating split systems
in 2 of 3 rooms solve this issue. However this is not a problem of this particulary apartment.
Overall - 5 stars.
