This has been one of the most comfortable stays I’ve had in Italy. Natzionale 51 is like a guess house more than a hotel. There’s no grand entrance like a typical hotel and you enter a low key main door like a local. You enter a Victorian era elevator to check in on the third floor. The receptionists were super friendly and welcoming. Our room was very large and quiet. Hotel internet was fast and consistent throughout our stay. The toilet was in a separate room from the shower, which was amazing, and the shower water pressure was strong and hot. The beds were very comfortable and our rooms were made every day. The location of the hotel was fantastic as well, right in front of some major bus stations for you to take to the main attractions, plenty of shops and restaurants near by, and within walking distance from the Rome train terminal, Trevor fountain, and the colosseum. We thoroughly enjoyed our stay and would come back here any time! The only slight issue was the elevator (which the receptionist said will be changed soon), it is a very antiquated elevator where the doors must be properly shut or else it won’t go up or down. It is also a bit small so only 2 persons max can go in at once. It can be a bit stressful during checkin/check out if you are in a big crowd or in a rush. But other than that, hands down, best stay in Rome!
