The staff in the hotel were friendly - though when we raised an issue did not really offer a suitable alternative. Executive lounge was nice, with great views of the Tokyo skyline. Luggage team were good.

Poor air conditioning - after spending the day in 36 degree summer heat, we would of liked a cool room. The air conditioning was poor - not what you would expect in a GBP750 per night room. I think we may have been given an older room. No offer of an upgrade, which seem to be given out freely for some people at check-in. This led to poor sleep. No plug at one side of the bed. No USB, USB-C sockets. Again basic stuff for a 5 star hotel. Dated electronics, no smart tv. Not worth the price paid. We stayed at other 5 star hotels in a Japan for significantly less, that offered significantly more. Not asked at checkout how our stay went. We raised the issues above during the stay, so did give the hotel and opportunity to rectify.

Very nice check-in experience. Must say the Lady Manager was exceptional in her making us feel welcome and explaining all the alternatives to us due to the fact that we were not able to use the Lounge per our booked preferred room. Very nice service in the Garden Tower 40F breakfast time; also had a shabu-shabu lunch -- again the lady serving us was super good. All in all, it has been very nice staying the Executive House Zen.

Nothing really. Everything was just perfect. Price of course may seem high but that is to be expected for such a fine room and service. Wish we had a chance to try out the Lounge. Maybe next time!

Lots of towers Gym reserved for 18 guests only The garden looks nice

Not sure the price is reasonable/ worthy. For the travelers who don't speak Japanese but only English, this might be a good choice.

Hotel is conveniently located, within 10 minutes walking distance you have 4 metro lines. The neighborhood is lively and there are plenty of restaurants, bars and cafes in the area. The Hotel itself is quite clean and most of the staff speak good English. The room itself is big compared to the usual room size in Tokyo's hotels.

The closet space is limited, which was quite inconvenient for us.
