Andera is super nice and communicative. She was able to let me check in early to drop off my luggage because room was already cleaned.
Her place is a bit small but I think that's how most places in Tokyo are. Her place is easy to find given her detailed instructions prior to check in and only 7mins from JR Otsuka station.
The only thing I wish I knew prior was that the washer/dryer, is an air dryer function and so you still need to hang clothes to fully dry it.
