I can definitely recommend June's apartment! I stayed for 8 nights on my first solo trip to Japan, and I felt very safe and at home. June was very quick to respond to any queries which also helped me feel safe travelling on my own! The apartment felt more spacious than I was expecting, and had everything you needed - I could have easily stayed for longer. The neighbourhood is lovely and quiet, and really interesting to explore (lots of lovely shrines and interesting looking restaurants, cafes, bars, etc, as well as plenty of konbini). It's also incredibly easy and quick to get to pretty much anywhere in Tokyo, as well as day trips slightly further away. I hope I can stay here again one day!
