We had an absolutely fabulous experience at Matsuri's place! I took my two young kids (5 and 7 years old) to Japan for the first time, and we stayed here with our friend and her young son (5 yrs old). For us, it was perfect! Neighbourhood is quiet and safe; check-in was very easy; place was incredibly close to Kuramae station(s) from which you can get pretty much everywhere; three grocery stores within 1 min walk; cafes, restaurants and even McDonalds for the kids very close by, and a kid-friendly park within 5 mins walk (Seika Park I think?); laundry in-suite; bathroom with small bath and lovely shower; full kitchen; nice balcony to take a breather; free wifi; great layout and felt like we had lots of space. Honestly, we were all delighted with it. We took an Uber from Ueno station on the first day, just because the kids were tired and we had lots of bags, and it was very quick (10-15 mins maybe?) but other than that, we used transit everywhere. Matsuri was very responsive to enquiries but left us to enjoy Toyko undisturbed otherwise. Would definitely stay here again.
