Elise was very kind and communicative. She was also flexible in her schedule, and she gave me a discount since I ended up having to watch their cats too. She's a great host!
As for the apartment, expect an old (D rated -- plastered on the front window) NYC building. The elevator didn't work more than half the time during my stay, so don't rely on it. The apartment smells like cats (even though I cleaned and cared for the litter box regularly). The cat hair is everywhere, and there were clumps of it on the floor. If that doesn't bother you, then you're good to go! It was overall a good spot for the price.
And the location is PERFECT! Right by a great subway stop.
