Really enjoyed our stay at IntheHood. I couldn't think of a better location for our first time in Tokyo than this. What you read in the description on this unit's whereabouts is true-- it's a short walk from Tokyo Tower and Shiba Park. It's also steps away from the Oedo (E) Line, which made taking the subway from the airport there relatively hassle-free. It's a walkable distance from Roppongi and the Rainbow Bridge (which you can cross to get to the popular Odaiba) and a few subway stops away from the very upbeat neighborhoods Shinjuku and Harajuku.
The Check-in process was seamless-- all coordinated through a tablet in the lobby of the building. Getting in and out of the unit was keyless, with a simple 4 digit code being our means of entry and exit.
The inside of unit was nice and minimalistic. Everything we needed was there, including an extra jug of water in the fridge. The bath/shower set up was spacious, and doubled as a hang dryer-- which proved to be a viable utility for our one week stay when used in tandem with the in-unit washer.
The guest manual was very informative for folks visiting Japan for the first time. It showed us everything from how to operate the water heaters for the sinks/bath/shower to a translation for the many buttons on the bidet. The heating system was also clutch given our visit occurred during a cold time of year.
The only drawbacks to our rental, and they are minor ones, was that there were only 2 thin very towels and 2 very thin rags given to us-- which proved to be tricky given our one week stay and forced us to used the in unit washer. And, it got a little loud from time to time-- we were right next to a highway so the volume went up during busy hours.
Oh, and one more thing-- the listing for this showed two different units in the photos. We ended up getting the second unit you see, but the photos for the first unit had a better view. So we were a tad disappointed at that upon arrival, but it was only a minor blemish to the overall stay.
TLDR: Our stay here was great. They gave us mostly everything we needed and the location was prime. If you're going to Tokyo for the first time, I'd very much recommend staying here. Just bring your own towel as a back up.
