the flat is nice, very clean and freshly painted, and Federico is a great guy. he was extremely helpful and you can tell he is striving to make you comfortable in his cute, very centrally-located apartment. the location is unbeatable, and the apartment is fine for 2, 3 or even 4 people. the sofa bed is just as comfortable as a normal bed. we had a noise problem which was not Federico's fault and he was happy to change us to a different place, which helped a lot. unfortunately, there are some partially unforgivable problems considering the very high price. everything about the first apartment was totally fine except for the rumbling 'mystery noise' that bothered me, but the second apartment (right next door) had practically no water whatsoever in the shower (any sort of normal shower was impossible), the bathroom door could not be closed (which can be awkward if you are not just a couple), and the AC would only work for about 5 minutes then turned off. in my opinion, those 3 problems seem a little too much when you are paying approx. 150€ a night, a "deal" for Rome maybe, but a lot of money nonetheless. everything else was fine and even great, and i would recommend the apartments if some or all of these details are fixed, but bring a good pair of earplugs, too. the street noise is pretty intense sometimes, but i suspect it is everywhere in Rome. i hate to say anything negative because Federico was great, but the almost-no-water-in-shower-at-constantly-fluctuating-temperatures scenario is a red line for me unless i am staying at a cheap hostel where you might expect something like that. as i say, that was only in one flat, though. in the other, the water and all else was just fine
