Taaj's place is convenient and easily accessible. It is about a 5ish minute walk from/to the 4th ave-9th st F & G train station. Otherwise, tons of restaurants and bars close by. In particular, try Casita of Brooklyn for coffee/espresso. They have a killer Cafe Con Leche. Luck Thai is very good. And for your ice cream fix, Van Leeuwen is near.
Just a note though on the accommodation. The room you will be staying in is quiet and cool. I would recommend bringing some sort of foam twin size mattress topper though, as your sleeping accommodation is a small futon. I'm 5'9" and it was too short in length for me. My feet hung off. But that was well enough for the price. Make sure you sleep to one side though and not in the middle. There's this very hard bar or something running down the middle and it's not comfortable to sleep on top of.
Don't be frightened of the toilet, as it does shriek loudly when you flush. It only lasts for about a minute.
Overall, Taaj's place is great. It's safe, relaxed and as mentioned, located well. He is a great communicator. Just beware the futon.
