Staying at Caroline's place was very pleasant. Everything is nice and tidy. Caroline's mother welcomed us, handed us the keys, and basically was our contact during the stay. She's a real polite and friendly lady. The neighbourhood can seem a little rough at first sight, depending on what you're used to, but we felt safe there, even late at night (although some loitering can be going on during that time). Manhattan can be easily reached by metro from the place (approx. 20 min). For me and my friend it was the first time in NYC and Caroline and her mother contributed to a great experience!
