We're 3 people who stayed here for 2 weeks. Checking in and out were seamless! The place is the biggest one we've stayed at.
Superb location; just seconds away from the station. You can walk to SkyTree! Matsuya—our favorite gyudon place—is on the same block. There's also Unazen nearby serving amazing unagi and Mugiwara with their awesome ramen.
Convenience stores are within walking distance. Also mini groceries like MyBasket and a liquor store that sells other beverages and necessities. Their drinking water is the cheapest!
What'd make it more perfect for next time is if the bidet in the toilet is installed by then (we already saw the power socket inside) and if the detergent and trash bags are enough for 2 weeks' stay (there was only 1/4 of the bottle left and the only trash bags were the ones already in the bins). Having small chairs would be nice too, since it's spacious, and maybe a floor mop.
But overall, we're very happy with the place!
