This is a really cool apartment in an absolutely ideal central location. We were able to walk to virtually all of the major sites, (except the Vatican which was a quick Metro ride away). Our host, Martina is super nice and very responsive.
Again, location was key - in fact there is a fantastic Cafe, and even better, one of Rome's best Gelateria's right across the street from the apt! (Gelateria Crema and Cioccolato). Wonderful Gelato!!
The apt. had a very nice air conditioning unit so it was nice and cool, even in a major heat wave (100+ degrees).
The upstairs bedrooms were great with lots of storage and power outlets everywhere.
I strongly recommend the Respighi Loft if you want a very nice and centrally located place to stay in Rome.
