Exceptional apartment, very clean, very close to everything, 20 minutes max walking distance to all major touristic places. Excellent communication by voice/text/email, can't get any better. Gaia welcomed us on arrival and gave us a quick orientation of the apartment, of what is close, as well as of the Rome sighs to visit in general. She also arranged for our transportation on return. Marco (her driver) was very punctual and helpful while charging only the normal fixed fee (side note: not all the taxis in Rome are honest, beware and ask for the meter before trip starts)
The apartment has a total of 5 beds counting the 2 extensible couches in the living, so it was more than enough for 4 of us, but it can accommodate way more. The small bedroom has its own bath, while the rest will be sharing the other one. Small but nice kitchen with a small freezer and small (separate) fridge, stove, microwave, moka and press coffee machines.
The only small pick would be the internet connection; the range extender in the kitchen gets stuck quite often and needs unplugging to get it to work again; not a big deal for us as the 4G wireless connection worked in the apartment on Vodafone.
There is a local grocery store on the corner as well as a pharmacy. Underneath there is a very good restaurant/pizzeria "Ristorante E Pizzeria AL Braciere" were we ate a number of times when short on time. The taxi station is also just steps away.
All together we can't be happier about the apartment and Gaia's services. If we visit Rome again, her place would be first on the list of places to stay. Thanks Gaia
