Having used other Mimaru apartment hotels across Japan, I would continue saying that the level of service is excellent all around.
We stayed in the Asakusa one the year before, but on this occasion we wanted to stay a little away from the hustle and bustle. The hotel is about 5-7 minutes walk away from the Ueno train/metro station via the Iriya gate tunnel and entrance.
The hotel doesn't have the walk out into the middle of the attractions feel, but if you want somewhere a bit quieter, and within reach of excellent transport links to other parts of Tokyo, this is a great location to stay in. You have Shinkansen, Yamanote JR line and Metro.
In the immediate area, there are not so many shops, being underneath a highway, but both 7Eleven and FamilyMart are just short walk away, and 5-7 minutes away are a selection of fast food, izakayas and independent eateries.
We had an unfortunate event which meant we missed our first night and the staff went out of their way to contact Expedia and claim one night of the accommodating back for us. Very impressed and grateful for the help there.
On a day to day basis, the staff were extremely helpful from providing amenities, suggestions of nearby eateries and things to do.
Top tip regarding laundry - there is a panda themed (the symbol of Ueno) laundromat within 1 minute walk of the hotel. Given the 3 machines in the hotel are in demand, the external laundromat is a lifesaver and I think has a better combined washer/dryer machine.
