The apartment is very clean, has a great decor and is conveniently situated just a few blocks from the Vatican and an easy 10 to 30 minute walk to most of the popular Roman sightseeing places. It was perfect for 2 friends visiting Rome for the first time. Public transport is easy to reach and the Metro is about 10 mins walk away. The apartment has everything you could need - espresso machine, toaster, and electric kettle. The temperature ranged from high 40s to mid 60s so we didn't need air conditioning or heat. The apartment and the beds were comfortable and you can't hear noise on the street. My friend is a very light sleeper and she was okay.
The street the apartment is on is great with yummy gelato and restaurants as well as little street supermarkets for water, fruit and pasta right there.
We had a few issues in the apartment at first but Guglielmo and his assistant Anna were very responsive and helpful so they became very minor quickly.
It is important to note that the balcony and balcony table & chairs are shared with one other apartment and contains a small closed off area that has a door that contains the shared washer dryer machine and cleaning supplies. This wasn't apparent to us when we arrived so we had to ask. The machine in the actual apartment space is broken with a note to use the one outside. Just be aware that European washer-dryer combos don't work like American ones so it gets it damp dry and then you have to hang it up to dry the rest of the way, but that's been my experience in Paris and Barcelona as well so it is not the fault of the apartment.
It was a great experience and my friend and I had a wonderful time! I can't emphasize enough what a great location this apartment is in especially if you are doing a thorough tour of the Vatican City. Great restaurants, gelato and wonderful sense of Roman life!
So thank you Guglielmo and arrivederci!
