This was my second stay at Treetop Haven with Maria Elena. The studio is charmingly adorable and completely private. The balcony is a lovely perk. Parking is easy and free. The location can't be beat; it's steps from the subway and from the buzzing local neighborhood shops and restaurants. Maria Elena is a fantastic host. She responds quickly to email and makes your stay comfortable without disturbing privacy. We didn't see Maria Elena during this visit (she lives downstairs) but she was readily available if we needed anything. 5 stars, highly recommended. Treetop Haven is my preferred accommodation in Boston. I'll be back.
