We spent two nights at the 4 star IQ Roma hotel and absolutely loved it. The hotel is located on a quiet street in the Termini area, near the Opera House, and a block from a metro stop.
The decor is modern, the rooms were good size--especially for a European hotel and immaculately clean, and the staff was very friendly and helpful. What impressed us most was that the hotel didn't try to rip you off for purchases such as water (.70 cents) coca cola (1 euro) or a bottle of wine (6 euro). The breakfast was an excellent buffet @$10 euro. There was even a self service laundry and a great rooftop terrace.
It was a real pleasure to stay here and we would definitely recommend it to anyone headed to Rome. We will return, as well.
