Which one?

We stayed at the Hotel Mystays Premier Hamamatsucho for 3 nights in the middle of September; it was an okay property with a good size room and bathroom. Negatives as you listed was the area didn't have a lot of F&B options but there were enough to get by and there was no laundry facilities so we had to go to a local coin laundry which was a bit expensive. Oh, transportation links were good.

Mitsui Garden Hotel Shiodome Italia-gai was in the same area i.e. block and half walk away so you'll get the same local atmosphere. Personal, I prefer the Mitsui Garden Hotel chain; we are staying at their Gotanda location with a big room and twin beds which are actually semi-doubles.

Mitsui Garden Hotel chain hotels do have nice public baths if one prefers that, but if one is staying at Gotanda, I think JR East Hotel Mets Gotanda right above the JR station is nicer, newer, and their set breakfast is really great with similar/lower price. I think the rooms are a little bigger too.

I stayed at Mitsui Garden Hotel at Gotanda once and their Superior Double room is rather small without much space to lay out a standard 28" checked in luggage.

Our triple room at mitsui in gotanda was a good size and the area was pretty lively and lots of food options IMO. The breakfest was very good!

Agree with you the location and we were hoping to get into the JR East Hotel Mets at Gotanda but it was full one day of a last minute stay for 7 days as it was over a holiday weekend. We had Moderate Twin at the MGH and it was good size room, enough to put out a suitcase and still could walk around it. I've learnt that twin rooms are always bigger in these hotels so this. But for location, you can't beat JR East Hotel Mets!

Is this a new hotel? I saw that article in my Google feed just before your post.

No, seems to be a rebranded hotel 2022 aug from "relief premium hotel" , which itself opened 2017

Whole hotel no smoking (prefer this over APA /smile hotel where the smoke smell may linger)

Is there any other kind of library?

Tokyu Stay Hotel Shibuya. Totally renovated as of September. Great location about 10 minutes walk from Shibuya station. Laundry in every room, kitchenettes, grocery store across the road. In a shockingly quiet location just minutes to Shibuya Scramble. Was much cheaper than anywhere in the area.

Now that the Courtyards have gotten so expensive, Mitsui Garden Hotels looks like a really good chain for me on paper.
While I'm OK with a slightly smaller room, my concern is that a lot of Japanese chains have beds that are too firm. Anyone with experience with this chain and can comment on how the beds compare to those at Western chains?

We live in Tokyo and travel often in Japan -- and we never leave home without our inflatable camping mattress pads - especially when we go to smaller cities with limited hotel facilities like when we visit family in Western Japan. Japanese beds are just way thinner and now that we are older it's unbearable as we are both side sleepers. These things work amazing - and are very light and easy to inflate / deflate. I was skeptical at first -- we are now believers...

Here's one similar on Amazon:

How do you inflate at the hotel?

The inflator is built in - You mini-jump / step up and down on the bottom part of the mattress - takes a few minutes but works surprisingly well - it’s all mechanical - thus the camping aspect.

Deflation is even easier - just open the air valve and roll it up - unlike other things that never seem to fit in the original packaging after use this one fits easily….

I'm actually trying to decrease the amount of stuff that I'm packing so if I have to sleep on a hard bed at a Toyoko Inn, then that's what I'll do.

Any place that has a Mitsui Garden Hotel has plenty of other hotels with reasonable beds so I don't have to force myself to stay at this chain if the beds are uncomfortable. I can survive at a Comfort Hotel or APA if the prices for major Western chain hotels in Tokyo get too outrageous.
