Our first big trip with our 15-month-old went off swimmingly thanks to Tammy's thoughtfulness and excellent accommodations. She was very responsive ahead of our trip and had the pack and play all set up when we arrived (for which we were very grateful as we were all quite tired after our travels).
Obviously in NY, you plan to spend a lot of time out, but Tammy's apartment is also a nice place to spend time. We really enjoyed the neighbourhood, with fantastic places to eat, plenty of playgrounds, and friendly people (the friendliest we met on our trip!).
We were pretty ignorant about NY, and our image of Harlem was really outdated, but we trusted other traveller reviews and felt very happy and safe staying at Tammy's place and being out and about in this neighbourhood. It's a lovely place in a fun, family-friendly neighbourhood, and honestly a nice refuge from the bustle of lower Manhattan!
