The location of the flat is great, good public transport links and a very nice walk to the centre of Rome. Lots of great restaurants in the area as well.
With regards to the flat, it's quite small and very dated. The chairs were on their last days of usability, the furniture was old and extremely used. Although the towels smelled clean, you could see that they have been used for a very long time - they had stains and marks on them. The bedsheets weren't much better either. We were also left with only one roll of toilet paper for a 4 night stay! Had to go out and buy some more... Please note that there is NO air conditioning, only a very old and poor fan which did very little to keep us cool. The terrace was lovely, but it is on the ground floor, therefore no views of Rome or the neighbourhood.
Guiseppe wasn't a particularly attentive host - he took a long time to respond to messages and wasn't very engaging. When we arrived, we got a very brief intro to key info about the flat. When we asked for advice about how to get to key tourist attractions, all we got was 'look at the summary sheet on the door'. The instructions he left on getting to the attractions were very poor and not helpful - we had to ask locals at the bus stop for help.
Overall I would recommend this area for staying in Rome, but not this flat or host
