First about comunication-10points,excelent, didnt meet Vincenzo but respond on every message in minutes, answer all my questions ets.
Location-good but not great (but you can see this on map so we decided to go here anyway)There is an hour and little more walk to piazza Venecia (center of rome) or to Vatican. Metro station is far away(30min Piramida station) and near is tram 8 but tram is not metro:) and line is not great for every part of rome and drives not as meteo quick and etc (so if you doesnt like to walk try another part of rome maybe somewere neer coloseum.
Conection from airport is great, just take train (8eur in one way) went out in Trastavere station and 5min walk to apartments 10/10
Check in is super, key are with Vicenzo frieds (Annamaria) she speaks english, open the apartmants, very polite, give us hints where is good to eat in neighb.10/10
Apartments is small but have everything, clean. But there is 2problems. First bathroom is so small, really small for anyone bigger then child, i's hard to wash hands even. And bigger thing, there is no kichen table, only coffe table (for balcony) neer the beed, so if you want to eat enything it is very complicated (we need to put food on the floor) advice to Vicenzo by the proper table and 4 chair.
Apartment is very well equipmend, has everythin even salt,coffe and oil🙌 It is clean. So overal, good value for the money, recomended for everybody who like to walk. Who wants nightlife etc.maybe is better to sleep in trastevere hert. so 9/10
