紧急求助，先谢谢了 ！！！

女儿在纽约上学，在曼哈顿租了一个单间（房租）1200刀，当时是month to month lease，房东口头上说可长期租，两年之内不涨价，我女儿也买了一点家具了。现在刚住了两个月，房东说，她妈妈（原来住三楼）腿摔坏了，要搬到楼下来，给了两方案：

1. You can vacate within 30 days.

2. You can move in to the one bedroom apartment upstairs (the bookshelves in the living room have to stay though, since I wouldn't have enough time to take them out. The apartment is mostly furnished and of course, has a kitchen.) If you chose this option, I can keep the $1,200 rent for an additional two months until you either find a place or chose to rent the one bedroom for $1,650 per month

请问我女儿一定的搬走 吗 ？或付1650到租楼上的吗？
