Erina's place is only 2-3 minutes walk away Kasai station (Tokyo Metro). There are lots of eateries and shops nearby. At least 2 supermarkets, 2 convenient stores and a 100yen shop! We even found our favorite second-hand game & DVD shops there too!
The best part is, you can take a 40-60 minutes bus ride to Haneda airport, Narita airport or Disneyland. The station is only 5-8 minutes walk away from Erina's place, no staircase and elevators involved! We were so happy to find that because it saved us from carrying our heavy big luggages all the way to airport by subway! The bus service is scheduled and usually on time. Free and easy!
There's also a retro cafe that serves amazing coffee (namely, charcoal coffee) and fluffy pancakes!
The room is a bit compact but it was sufficient for 3 of us. Recommended for neat and tidy travellers. If you keep your things in place, you'll be able to enjoy this cozy & convenient stay.
