My wife and I stayed at Chieko-San’s place for our two week quarantine and had a great time staying within our “zone”. There’s a Summit Grocery Store close by, France Tei Cafe, a little produce store, and Indian Restaurant all within a minutes walk.
Our little apartment was well equipped, cozy and everything you needed to cook is available. So if you are staying in that part of Tokyo I’d stay here again in a heartbeat. Take care and enjoy your trip!
