The location is really good, close to several subway stops as well as Times Square, 5th Ave, the High Line, Chelsea art galleries, etc. If you are a walker then it is good jump off point for farther locations. Antonia's apartment is very clean and safe. The bed is a touch small for two people, depending on how you like to sleep. It was a bit short for my husband who is tall (6'4").
I ended up doing a job interview via Skype while on vacation and the wifi connection was excellent. That Antonia also provided breakfast and coffee made that morning stress free.
Antonia loves her city and offers a wealth of information. If you are at all confused on what you want to do, ask her for the details. She is an excellent resource! Check out was easy, which is exactly what you want when trying to get the most time possible out of your holiday city.
