The rooms are kept very neat and clean. The staff is friendly and responsive (we needed our microwave changed and a toaster added, and it happened within a day). Ray and Stanley, in particular, are very welcoming. The location couldn't be more convenient for grocery stores, restaurants, train stops (including Grand Central), and of course lots of companies and offices (including the UN).
The WiFi can be a bit spotty, but I think the managers are working on it.
