First and foremost, I must say that my comments would have not have been so good if it were not for Jerson (the employee at reception), who worked very long hours to keep everybody satisfied in respect of breakfast, cleanliness and proving various travel information, as if he was in fact the owner. As for our stay, overall it was a good experience. The rooms are quite close (5 mins walking distance) to both Termini and Vittorio Emmanuele metro stations, which are on the same line that ends up at the historic centre and the Vatican. Via Merulana itself is a street where you can have an enjoyable night (food and drink) if you do not wish to head to the metro and worry about the 11.30pm curfew. The rooms were extremely clean - we stayed there for six nights and we lost count how many times our room was cleaned (maybe more that once in a certain day). Breakfast consisted of coffee/milk, fruit juice, fruit, cereal, yogurt, fresh croissants, many (more than 4-5) kinds of packed cakes, toasted bread with ham and cheese, bread with an assortiment of jams and mini portions of Nutella.
It would be fair to say that firstly, the fact that it is situated at a non-walking distance to the historic centre (most tourist attractions) must be taken into consideration by any traveller who wishes to have them at hands' reach. Still, it is up to personal preference and it is not Chroma Suites (doorbell:Chroma Design Rooms) that should take the blame for that. Secondly, all (five or six?) rooms are situated around a common reception area, which means that people who stay at the rooms may be able to hear other people having conversations at the common area, the employees talking on the phone, the doorbell (which must be rung in order to enter the block of flats where the rooms are located), sometimes before 8 am and after 12 midnight. However, as there are not a lot of rooms, these are limited. Lastly, only because there are people that might be annoyed, personally it did not bother me at all, once you are in the room, at the quiet of the night, there is a slight ticking noise, probably from the electric meter, as analogue alarm clocks tick.
