We had a great time at Grover's house. It was big and spacious and close to the subway. At the end of the street, there's a cafe called Lenox Sapphire which is a nice spot for breakfast. There's also a really popular restaurant called Red Rooster nearby but it's always full and you have to book in advance!
Grover was amazing at communicating and we had no problems whatsoever with our stay.
The only downside was that the flat is a bit noisy (especially in the bedroom facing the street).
