Hara's place was spacious and comfortable. We fit 6 adults, 3 on the beds and 3 on futons, pretty comfortably. If you're not used to staying in Tokyo sized places then you might feel cramped with that many people, but we were fine. It's near the station and there are several convenient stores in the area. There are two supermarkets just around the corner a My Basket and Piago. It's also around an area with a lot of food options! They amenities they provide were great as well! They had water bottles, face wash, tooth brushes, etc for us! The only downside is that down the street there was a building with a live house so some nights you could hear people outside, but it wasn't too loud!
Hara also responds quickly to any questions or concerns we had. Be mindful of others staying on the other floors with how heavy you step. Also no elevator so make sure you can carry your luggage up and down the stairs!
