The room is very big and has lots of helpful tips and maps..same with Sergio, he was happy to offer directions and answer questions. The location of the place is okay, there’s not much to do in Testaccio but it’s close enough to Trastevere, which offers a lot to do. The main parts of the city though were all quite far with public transport. My biggest qualm with the place was that Sergio charges guests to use the amenities that in my experience are usually free. 6€ to use the washer and soap, 5€ to use the oven, even 1€ to use salt and pepper! I understand this is a business, but that just feels cheap to me.
