This place was exactly what we were looking for! Low key, inexpensive, a decent place to crash for the night. Nothing fancy or extra here but that's what we wanted. Loved the traditional style rooms with tatami mats. We traveled with a baby (6/7 months old) and the room was perfect for her to crawl around in. The only downside was that the walls are super thin, so if you want your baby to sleep through all the noises coming from the rest of the house, bring a white noise machine. We did! And it was a definitely a necessity. The house is old and squeaky! We loved that about it though, it definitely had it's charm. Can't speak on the kitchen as we didn't use it. We spent our days out and about so we didn't spend to much time indoors. The bathroom is ... a bathroom lol. The shower and tub was in good condition and worked as it should. It was the typical setup. We didn't use the washer for our laundry since we weren't home long enough to hang up our clothes to dry, so we utilized the 24 hour laundromat a few blocks away. Very convenient. I loved how close we were to the asagaya train station! I enjoyed the 8 minute walk every day. Even in 100 degrees weather! I wish we spent more time exploring Asagaya itself, but we definitely loved how close we were to everything in Tokyo. The Shinjuku station is so close and from there you can get anywhere. Basically this was the perfect place to have a home base.
If you are traveling with a baby or you are sensitive to noise, keep in mind that the other guests may not be aware or consider how loud they are moving around the house. That's all!
