Reina's location was 10mins away from the Tokyo Skytree station, which was convenient for us on the rainy days. She allowed us to check in early (about an hour early), and let us keep our luggage in the lobby of the building until 2pm on the day of check out, which helped tremendously when we wanted to peruse the area without bringing our large luggage with us. Which was awesome!
The one comment I do have with the building is that there was no access to an elevator so we had to carry our heavy luggage to the 4th floor. So definitely pack light if you plan to stay here.
Otherwise, our stay was short and sweet. Reina was also very responsive when we needed to hear from her.
