Absolutely amazing stay in Rome. Carl is as helpful and understanding as possible, or even more! :) We had flight obstacles but together with Carl we found best solutions. So speaking about host - you will not find better one ;) About apartment - absolutely astonishing flat, right in the center of Rome, 30 seconds walk from Campo di Fiori, 5 minutes walk from Piazza Navona, 15 minutes walk to Vatican etc. Purely fantastic location! About flat itself - beautiful, cosy, clean and other compliments ;) IF have to find any inconvenience for others to consider - flat is on the 2nd floor without elevator, but it did not matter for us at all :) To sum up - 101% recommendation from our side :)
