Daigo’s room at Ciel Hills is more like an apartment, including a kitchen, toilet/bathroom and a big balcony. Everything is new and it was perfectly clean.
We found it a great place to stay in Tokyo for a couple (with the sofa-bed even 4 people can sleep there).
The bed in the the room was very comfortable and the toilet/bathroom was very spacious. There is also a washing machine and you can dry the clothes in the balcony.
The place is located in a quiet area very close to Tokyo Skytree and the subway (aprox one hour trip to Narita and Haneda) so it was very convenient for us.
Communication with Daigo was perfect as he replied very quickly to all our questions. Check-in is straightforward via a pin code, although we even had the chance to meet Daigo in person.
All in all, a very good place to stay in Tokyo for a reasonable price!
