Sumifuku's place is AWESOME! This is a must stay place. They also have many other similar rooms. This is my second time at this apartment AirBNB and won't be my last. The location is superb, close to transportation, eating, daily shopping (groceries and eateries) and convenient to Shinkjuku and the JR lines. The best part about this apartment is that it has 3 distinct spaces and feels very roomy. There are sliding doors to close off the bedroom with 2 beds for privacy and then a sitting area with a futon sofa for lounging or other sleeping areas. The AC is excellent with 2 units. I also appreciated having a kitchen and especially the washer for a long stay. Also, by Japanese standards, the bathroom is pretty roomy. This unit is in the city so there are city noises. This unit is super clean which I appreciated. You do have to walk up 1 flight of stairs to get to the elevator, but it's not so bad. This is Japan afterall. I truly appreciated the host's communications and the ease of finding this location along with how easy it was to get into the apartment. GREAT STAY! I appreciated Sumifuku and will be back for sure!
