I couldn't recommend this place enough, my only negative is that we didn't stay longer.
First of all, the host Francesco is excellent. Great communication leading up to the stay. When we arrived he took some time to tell us about some must see spots across the city & recommended some great places to eat/drink.
The apartment was more than I had hoped for - it had everything we needed & some extras. A few beers in the fridge & some breakfast for our first morning were a lovely touch.
It was in the perfect location - almost everything we wanted to see was within a 10-20 min walk. Some of the local restaurants and bars were great too, if you didn't want to venture too far.
Me & my girlfriend stayed for 5 days/4 nights, we wished we'd stayed longer. All in all, a great place, great location & even better host.
P.s. Make sure you venture across the water to Trastevere for a very authentic Italian feel, with great bars & restaurants.
