We booked Ostay-Jennie 3 weeks before our trip because of a last minute cancellation made by our prior Airbnb. Price was good being last minute, and the host was very nice and responsive. Location was great, about 12-15 min walk to Ueno station, the park, and Ameyoko shopping district.
It was small, but just enough for a family of 4, and had the bare minimum that you needed (beds do not look like photos, fyi). The downside was that the beds were very hard and you can feel the springs right under you. One bed had a topper and we noticed the other two under the bed, so we pulled them out, put them on and they helped a little.
It rained a lot while we were in Tokyo, so the washer was very convenient. We asked about a dryer and the wet room (shower room) IS one! The whole room becomes a dryer which was a life saver to dry our soaked shoes each day.
Family mart & Lawson’s nearby for late night snacks, great ramen place around the corner, and a beautiful shrine right behind the building.
