My friend and I stayed for 4 nights at the Palmer Square 2 bdrm in mid-August. The apartment is beautifully decorated, very bright, and open. It felt quite spacious for the 2 of us. The location is fantastic, quite close to Mediterra, the Halo Pub, Mistral, Teresa's Cafe, and The Bent Spoon.
James, the host, was incredibly responsive to queries. For example, there was no colander in the otherwise well-equipped kitchen (I prepared French omelettes for breakfast, and we cooked a nice supper one evening), and because we had fruits and veggies from Terhune Orchards (near Princeton) to wash and pasta to drain, I asked James about it. Within just a few hours of my query, James left a brand-new, high-quality stainless steel over-the-sink colander at the property! Fantastic! James remarked that there had been a colander in the kitchen previously. Note to guests: please don't take stuff from VRBO properties.
I was initially concerned that the apartment would be on the warm side since it is on the second and third floors of the property, and we were in the midst of fairly hot temps in mid-August, but the central air conditioning was very efficient.
Overall, a very pleasant place to stay in Princeton. I'd definitely rent it again!
