Billerica is a pleasant, family-friendly suburb of about 42,000 people roughly 20 miles northwest of Boston with parks, Nuttings Lake, historic village centers, a growing biotech/tech presence and MBTA commuter‑rail access—so it’s comfortable, safe and has enough local amenities to keep multi‑week stays interesting.
For bigger-city options, Lowell (historic mills, music/arts and a lively dining scene) and nearby Boston (museums, sports, nightlife and major hospitals) are easy drives or commuter‑rail trips for weekend escapes and extra entertainment.
