Ok, so I read reviews for this hostel on a few sites and they all said good things, but I thought it couldn't be that good. Well it is. I stayed in a room with 6 bunks (20euro/night) with ensuite bathroom (the only problem with the hostel - no towel hooks in the bathroom/shower!!). The room was clean and warm and everything I expected.

The common areas were clean and nice and the DVD player got used a lot (walk round Rome til 4.30-5ish and then crash out with a few dvds, beers and people from around the world, the best!)

The kitchen was a kitchen!

The breakfast (inc. in price) is brill and not promoted enough by the offical website. Rolls, meat, cheese, yoghurt, cereal, juice, fruit, tea, coffee.... eat lots in the morning and then gang up with some people and cook piles of pasta in the evening (eating out in Rome is expensive).

Visit the tourist attractions (Col./Forum, Vatican, Trevi) at night when they are lit up and looking very impressive!

Yellow Hostel: well worth going to if you are in Rome.

PS They accept credit cards but charge 5 euros for the priv. (though given the exchange rate my CC gave was still cheaper than cash!)

On the ground floor is the Hotel Corallo, but upstairs is Yellow Hostel, a place for the discerning budget traveller with lots of character, funky colours and very friendly and helpful staff who speak an amazing array of languages. We were happy to come to a place where very good English was spoken!
Yellow has a really comfortable lounge which turns into a bar and movie room at night. They also arrange something to do every night - Pub Crawl, Pub on the River etc. and their recommended Rome(ing) tours operates two fantastic tours of the old town - (go to the front desk and ask them) - one is St Peter's Cathedral/Vatican/Sistine Chapel and the other is of the Forum/Colluseum/Pantheon. I went on the Vatican tour and the tour guide (Chris) was an absolutely amazing walking encyclopedia of facts and fun over four hours. Check out his Star Wars imitation!
We met tons of travellers there, the price was pretty average and the kitchen was clean. Lots of people cooked meals in the evening. We had our full juice container stolen out of the fridge which was annoying. The free internet rocked. Dorms are not segregated and we were the only two women in with 7 other men. The only thing I was a bit concerned about was the safety, (even though there are lockable bins under the beds and lockers) because other people had passports/credit cards stolen while we were there. There are key cards to get into the dorms section and you have to ring to get in at night (no curfew and open all day). Check in is at 1pm which is a bit of pain because in most places check-out is 10am. but there is a rack where you can store your bags.

Amazing place, I strongly recommend it to everybody. Easily the best hostel I have stayed in. The relaxed atmosphere really makes you want to stay indoors and not see Rome, that is a pretty impressive effort in my book! Anyway the walking tours, really helped me to discover Rome.

Yellow hostel is clean, in prime location, full of fun people, and full of character. I would highly recommend it to the average American college graduate or year-abroad student who wants to get the most partying bang for the buck. The common area at Yellow is funky and chill - playing music like Dave Matthews and Jack Johnson, playing DVDs like Old School, and full of people hanging out, drinking, playing the guitar and surfing the internet. You can buy drinks at the front desk.

However, having traveled a lot and been in many hostels over the years, my favorite thing about traveling is meeting a diverse group of people. You won't really find this at Yellow Hostel: it's a haven for Americans who are seeking their comfort zone in a foreign country. While I thought many of the people there were friendly, I didn't go to Rome to meet Americans. I spent most of my evenings wandering around other parts of Rome, trying to get a feel for the city itself.

If you're homesick and dying to crash with a bunch of laid-back people who love Budweiser and college football as much as you do, you'll LOVE this hostel!
