Max is perfect host, take cares of his guests very much. He's very helpful, he gave me lots of tips about local food and places around. All my stay in Rome and before arrive, I could contact with him on Whatsapp, and he answered me all the time.
About location, the pigneto is fantastic province. You can feel there soul of Italy. Lots of local food and wine in very good prizes, much cheaper , than in the centre. Around the flat is metro station, so you can get to the centre and on the others part of Rome in few minutes.
About apartament - clean, comfortable, maybe little small, but rest is ok ;)
I recommend!!
