Our stay at Merulana Star was in general a good experience. The location was the highlight, as it was just a 10 minute walk from the Colosseum, with great links to transport. The room itself was a great size, the bathroom was nice and clean, and it even came with a small mini fridge to store drinks and snacks. The only downside was the noise, not from the main street location but from the other guests inside. They were very noisy at around 3am making it very difficult to sleep. But overall a good experience.
