We mostly enjoyed the apartment and loved Ebisu. The only difficulty was the thin sleeping pads and thin pillows, which were extremely uncomfortable. It made fully enjoying the apartment fairly difficult :( We inquired if they had additional padding and they said it was “out of stock”. It seems something that is easily fixed would make the apartment much more enjoyable for their guests.
The bathroom was great, and washer/dryer was very convenient. The building was clean, bright and peaceful, although it seems to be all AirBnB rentals.
The neighborhood is amazing. I am now in love with Ebisu, even after visiting Japan 30+ times. The walk to either Ebisu or Hiro-o station was always very pleasant.
Finally, the host was always friendly, with quick responses. Check in and out was super easy, and the building is easy to find. So, all in all, a positive experience, except for sleep comfort.
