Marina's apartment is beautiful and quite spacey, has all of the amenities one might need including air conditioning in every room (which is super relevant in Italy at summer time) We really enjoyed our stay in there, the metro is really 5 minutes away, so is the supermarket, the area around is not very touristy but all the tourist places are easily accessible.
Can recommend the apartment to anyone looking for a stay in Rome, especially if you're there with kids.
