The Treetop Haven is a real gem to stay at! I stayed here for over 5 weeks while working hard to complete my thesis. It was very comfortable and had everything I needed. It was so great to wake up in the mornings and have a cup of coffee on the sunny balcony overlooking the trees. The location is great, very close to lots of green spaces including Jamaica Pond and Arnold Arboretum, public transit, and lots of good (and affordable) restaurants nearby. Maria Elena is a very thoughtful host who was always quick to respond if issues came up. Highly recommend!
