I stayed at this place for 2 months and never saw Momoyo. I'm not sure if she exists, but the man who is the actual host is pretty nice. The place is in a great location. It's about a 3-minute walk to the subway, and there are lots of yummy restaurants around and places to buy all of your groceries within walking distance. There is also a big shopping mall within walking distance. The room was small but cozy. It's nice to open the balcony door and let the breeze in.
However, the balcony does have a problem with clover mites, which could possibly be seasonal. They do sometimes get into the room and you catch them crawling on you. There is no ac included in the price. So, unless you want to add $90 to the monthly rent, you may suffer from the heat in the room. There is a cleaner who comes occasionally, but most of the cleaning is left up to the guests. Therefore, depending on your roommates, you could have to tolerate some dirty or messy habits. The hired cleaner could also be more thorough with the occasional cleaning. I don't think the dirty dish towel was changed once during my 2-month stay.
Overall, I had an okay stay at this place. :)
