It is a good small place that is convenient to its metro stop. The metro stop in turn is convenient to about anywhere in western Tokyo (Shinjuku, Shibuya, Harajuku, Omotesando, Ebisu) but getting ti Eastern Tokyo (Ginza, Akihabara, etc.) feels like a bit more of a trip but is still totally doable. I was there during an historic heatwave, so the air conditioner wasn’t quite strong enough to keep the place cool, but I think it would have been okay during any other weather. The neighborhood, Honancho, is cute and old-timey, but has all the amenities you could need very nearby.
Seagull-San is very nice and fun. Thanks for the stay, Seagull-san!
