I definitely recommend Musa House, particularly for groups of friends. I traveled with three friends and it was great to have our own bedrooms and bathrooms. The apartment was really clean and modern (including modern bathrooms). The beds and pillows were comfortable. The common space was large enough to be comfortable during a bit of down time. We didn't cook but the kitchenette was nice. The location was great. We liked the neighborhood as it had lots of shops and restaurants and the Spanish Steps one block away. There was a taxi stand across the street which was really convenient. We took taxis for about 8-12 euros to the Vatican and Colosseum. We did walk back from the Vatican stopping multiple places along the way like Pantheon and Trevi Fountain (otherwise, I think it would have been a 30 minute walk straight there). I liked that there was a keypad entry so it was very easy to arrive as we could go straight in and not have to worry about meeting a host. All in all, I would definitely return!
