hello! may in new york is usually lovely so you picked a great time to go! personally i don’t live in new york so i can’t give you the best answer. i usually stay somewhere in midtown, just so its really central & i usually walk everywhere unless i plan on going a really long ways. this way i can usually take different routes everywhere, stop at different shops & places if i choose to. the bar PDT is always really cool, there’s a section of the berlin wall to see along with numerous parks people don’t know about, walking around west village (magnolia bakery is amazing if you have the time - usually a line) and basically all the neighborhoods have such a different vibe & feel that when you find your favorite area you should take some time & really explore it, and of course there’s a lot of things out of Manhattan that most tourists usually don’t visit to consider!
