I recommend Williamsburg to everyone if visiting NYC. This is my second stay in the area - the other was around the block. I love the proximity of transport links - metro and river ferry - and great shops and restaurants nearby. Please note though there are works on the L train route so it’s not as convenient as it can be / you just need to be make sure you read the signs at the stations.
The apartment is cosy and had all you need. There are 2 flights of stairs which is a challenge with luggage but at least you only have to do that once!
Washing machine was hot working when we were there but as this was the first stop in our trip we didn’t need it.
Water, iced tea and snacks were nice on arrival.
