The apartment is in a great location - near metro station which is very important in Roma, 20 mins away from Colosseo, in quiet neighbourhood. The person who met us at the apartment to let us in was great - gave us some tips about Roma and was really friendly. The hosts seem very nice too. They have arranged personal pick up for us from the airport (60€).
Everything was great exept I did not enjoy the apartment itself. Pictures here look way better that it actually is. It already requires cosmetic redoing of walls, doors. Requires new furniture - for exapmle cabinets, new bed, because of them made terrible noises, also I would mention new sink counter in the bathroom and even new shower because you can tell that they are worn out. Above all - it was really cold in the apratment (we were there in the begining of October) and there was no way to warm it up. For me - I really prefer to fell warm and comfortable even though we were out in the city at most of the time.
So to sum up - it did not statisfy my personal needs and I would not go back, but if things mentioned above do not disturb You - there are benefts too that I wrote about firstly.
