A part of my luggage case had loosen during travel and the hotel staff was so nice to lend me tools to fix it. The only thing was the staff didn't allow me to do it in my room so I had to laid out my stuff in the hotel lobby to fix the case, which was a bit embarrassing since there're other guests and staff nearby. I see no reason for not being allowed to do the whole thing in my room and return the tools afterwards.
Other than that, the hotel is close to Ueno JR Station. Same size as a typical semi-double room in other hotels. Bathroom is larger than expected with bathtub equipped. You can get a spa pack from the front desk for free.
