I stayed in viainn higashi ginza for 12 nights. Everything worked perfectly for me. The room is quite small but it has everything that you need, airconditioning, tv, water boiler, the toilet has a bathtub and a shower. The toilet seat is the typical japanese one that has all the extra settings and flavours you could want. Breakfast was nice (It's quite a heavy breakfast but that's also a good thing. I tried everything that they offered + they have a coffee and a juice machine. They play lounge type music which is quite relaxing and I also heard a Finnish song here which was totally random). The hotel also had a ice cube machine + a laundrymachine in the 9th floor i believe? The ice cubes were free, and you could do your own laundry there for 100 yen which was super cheap. I didn't use this tho but it's a nice bonus. The hotel is opposite to tsukiji fish market, and that's worth a stroll. Also quite easily accessible through hibiya line and ginza line.
The room service worked really well, and every day they made my bed + changed the towels. The rooms also have slippers and a bath robe + an amenity kit with hairbrush, toothbrush and something else which are also daily changed if you used any of them. They provided shampoo, conditioner and a body wash which were all pleasant.
Free WIFI which worked super well! no complaints!
