We arrived at the Grand Fresa after a fairly long trip inside Japan. The room was ready early and they upgraded us. I can't praise this place enough. We obviously had a massive room, the suite we were given actually had two rooms! I originally booked a superior room, as I was concerned the basic rooms would be too small. I didn't see any of those rooms, so I'd recommend doing this.
The staff are great and helped us with 2 phone calls that required local knowledge. Free Wifi in the Hotel Lobby and loads of convenience stores around for Breakfast. We were exhausted and this Hotel provided the perfect remedy. It's in a fairly quiet location and is next to Akasaka station.
