The appartement is wide and well equipped. It has also an excellent location (3 minutes to the Oshiage Station).
Unfortunately there is only one bathroom but 3 toilets. And some rooms lacks curtains, so you will have a big wide sun at 5 AM...
There is an elevator, and plenty place for your belongings and luggage.
The host speak perfectly English and aim to answers all your questions.
There are towels and dishes. The fridge and the microwave are very useful.
A good place to stay.
