TL;DR: two of us spent a month here and it was fantastic.
Our highlights:
1. Lots of space. two bathrooms, patio (!), office, huge bedroom, living room. Everything is very modern and nice.
2. Free good-quality laundry.
3. Great Wi-Fi, easily capable of video conferencing. I was working from home from time to time, so it was a bliss.
4. Very nice shower and a huge bath.
5. Bedroom and office have black-out curtains, so you can sleep late easily :)
6. Great location. In a radios of 15 minutes walking around the apartment, we enjoyed:
- countless fitness activities (solidcore, pilates, HIIT, hot yoga, barre, rowing, cycling, climbing,...)
- very nice jazz bars
- 2 kava lounges
- numerous coffee places (we checked them all; ended up loving BlackStar coffee the most!)
- lots of nice cocktail bars
- upscale, mid-range & low-key restaurants. Lots of healthy options (my favourite is QUINOA in 4 minutes walking)
- boba teas, smoothies, fresh-squeezed juices
- multiple coworking options (including wework)
- nice grocery stores
- a park!
We stayed on Manhattan a few times before, and it was our first time in Williamsburg, but we definitely liked it over Manhattan.
Overall, highly recommend!
