We stayed for one week with our 8 month old baby at Liza's. We lived in NYC for 16 years and were back to visit friends.
Liza was great and easy to communicate with and the check in was very easy.
The apt is in the heart of Williamsburg, just a short walk from Bedford Ave train and many restaurants/shops. The apt was bigger than we expected with a very nicely decorated living room. Liza did have all the things that someone with a baby needs (high chair, toys, crib etc), however, I would not recommend it for a family. I would suggest this as a place for someone young without a baby, who does not mind the loudness of the neighborhood that can be heard from inside the apt. There is a bar right opposite that stays busy and loud till morning hours as well as the noise from the backyard of the restaurant next door.Its also a second floor walk up, so we had to bring our stroller up and down the stairs.
The apt could improve on cleanliness in some areas. For the price, you are definitely paying for the location. I know that rents are high in that area, but we would opt into staying somewhere else next time.
