We had a perfect stay, nice and clean room and good facilities! It's right next to a big street, but you hear no noises at all! Very close to Colloseum, but keep in mind it is not in walking distance from Tastevere/Pantheon/Trevi fountain (metro is super close anyway). You can get free breakfast (coffee and pastry) at Materia Cafe, which is close by. Sadly we only found out about his during check-out, after we went there 2 times (still super cheap and yummy, so no problem).
