There were 3 in our group and the unit felt very spacious. Separate toilet and shower was helpful. There are two separate bedrooms with good sized beds, plus there is a folding bed for extra space. The unit was convenient for errands, but was a bit far for our walking taste (especially with suitcases). The host was very responsive. I would stay again, but just plan for a good walk to and from Iidabashi station.
