Rose-Marie is a most gracious host who goes the extra mile ( such as buying us almond milk for our breakfast) and providing useful suggestions to accomodate her guests.
The apartment is roomy and near a subway but it is garden level (read: basement) and consequently quite dark.
The lack of a kitchen sink might be an issue to some. The host's attention and helpful attitude make up for any negatives. She is, hands down, the best New York host we've had so far.
