Well-located, mid-priced, with a simple, chic interior - The Carvi is a great find.
The rooms are small (think European-size) but clean, modern, and comfortable. Most New York hotels in the same area will cost much more or be far less satisfactory. And what you're really paying for is the excellent location - walking distance to 5th Ave, Rockefeller Plaza, key metro stops, and numerous restaurants.
The only downside of my stay was the service - one employee in particular (Marcos, the evening receptionist.) Upon our arrival, we found our toilet did not flush. When we came down to report this incident, he was completely disinterested and said they were all booked and couldn't switch our room. We called hotels.com to report the problem, and THEY then called the hotel to demand something be done or they would find us alternate lodgings - at which point the receptionist rang our room to say "we'll send a plumber in the morning, for now just come use the restroom in the lobby." The problem was fixed (at 8 pm the following evening), and the rest of the stay was without incident.
Overall I enjoyed my stay at the Carvi. Aside from one employee's lack of customer service, the hotel offered clean, pleasant lodgings for a decent price point.
