Can't recommend this place enough! Stayed for over two weeks and it met all our requirements. It was very clean, comfortable and had all the necessities you would need to for a medium long stay. The area around Heiwajima had plenty of interesting spots to explore, with a park, a big onsen nearby (BigFun) and lots of restaurants around Omori station (20 min. walk). The only thing worth noting is that it is very easy to hear neighbours and could be quite noisy. Don't expect you'll be able to talk too loud at night if you don't want to bother your neighbours.
