The staffs were very friendly. I asked so many things before I went to the hotel (via email) and when I stayed in the hotel (asking for hair iron, scissors etc). Though it needs 30-40 minutes to go to popular places like Yamanote line area, but the area around MyStays Omori Hotel is already nice for me (not crowded too), you can get to Seiyu, Atre, even the park near the hotel is very cozy for me to look around.
