Okay, so you're going to New York City! No one visits to stay in their room. With that said, Iradj's place is just what you need. It's small, immaculately clean, and amazingly located.
Number of Guests: There were four of us--two married couples. Despite the small size of the apartment, it didn't feel too crowded. Perhaps this was because we spent very little time in the apartment.
One inconvenience is that the restroom is accessible only through the bedroom (look at the diagram Iradj has posted). So your pals will need to trek through your room as you're sleeping to use it. But even this was no big deal. We laughed about it. I used ear plugs and was totally unaware that my friends used it while I slept. And that's saying something because the toilet's flush is loud!
Availability of Host: Iradj is there (with a pleasant smile) if you need him.
Check-In/Check-Out: Iradj was willing to allow an early check-in so that we wouldn't have to drag around luggage for a few hours due to our early arrival. He also allowed a later check-out. Of course, if other guests are due to check in, this may not be available. However, he was able "and willing" to accommodate us.
Location: What can I say? You've heard the saying, Location, location, location. Well, sorry, but, "location, location, location." Iradj's place is perfectly located. It's smack dab in the middle of Hell's Kitchen. Restaurant's everywhere. Literally several up and down his street. We ate at the Galaxy Diner on the corner twice for breakfast. Was great!
You're within a ten-minute or so walk to Times Square, perhaps 25 minutes or so to Central Park, and maybe 15-20 minutes from Penn Station. Can't beat it!
All in all, no need to hesitate on this one. Grab it while you can!
