Ryota's place deserves a special mention on AirBnB. Where else can you can a room with a Grand Piano all to yourself, and soundproofed to -80dB? Music talk aside, the room feels a little crammed (yes, this is Tokyo where rooms are tiny), but the piano takes up a lot of space and that leaves very little room for luggage. Fully equipped, incl. a clothes washer, microwave and all provided with detailed instructions in English. Reasonably close from Ikebukuro (8 mins walk) which is on the main Yamanote JR line and where all the foodie and night life action is. Overall recommended highly for musicians or those travelling light.
