The Metropolitan is in an ideal location next to Ikebukuro station, which is a main terminus including the express train from and to Narita airport (there is also a limo bus service direct to the hotel if you have a lot of luggage). It's a quality hotel with several restaurants, good rooms, free newspaper each morning and very clean. The staff speak good English.
The only minor drawback we found was that, like other hotels in Japan I've stayed in, the room rate does not include breakfast and the cheapest breakfast at the hotel was 2,500 Yen (around £18.50 GBP) each. However, there are plenty of cafes nearby where we breakfasted for around 1,000 Yen each. Also the price to use the pool & gym put us off using it because we only wanted to use the pool.
However, we would definitely stay there again.More
