Overall Sonder Battery was a pleasant stay for us. The booking process was straightforward and the customer support team really helpful in ensuring that we get the room with the City View on the higher floor.
Room was actually bigger than we expected and had all the advertised amenities. Room Design is minimalistic and rather simple, but it really has everything you need for a week stay in NYC.
Some negatives important to point out. It is cold in the room and the only way to warm it up is the AC unit, which when switched on sounds like a 747 jet, so you can't really keep it on during the night.
Room was mostly clean, but there were some stains on the bed sheets. Bed itself was shaky due to several boards being broken, so the mattress kept sinking in.
Location is both a strength and a weakness. It is 30 min commute to the main sights, but multiple stations are less then 3 min away. Enough shopping and food around. Area is quiet.
Overall rather good price vs quality. Recommend
