I will split this into the good and the bad:
The bad - this place is a small efficiency near the top of an average apartment building in a HIGH RENT location. If you are older and cannot navigate steps comfortably - move on. My spouse and I are marathon runners and we were a bit winded by the narrow winding staircase when we got up there. You have been warned. Once you enter the unit you will be struck by its size. The average hotel room in Vegas is bigger - having said that it is well designed for 2 people - three makes is tight unless the third is a small child.
There is really no place to cook anything except continental breakfast in the room. There is a convection microwave and small cook-top but you are really not going to do much here except reheat leftovers. Realistically though that is all you need it for.
Get to know your neighbors - you will hear them along with the pigeons. Bring earplugs and all will be forgiven.
The shower and bathroom are tiny but functional. Drop the soap? You will need to open the shower door to pick it up! BTW bring your own large bar of soap as they ration the tiny bar you get on arrival.
Fancy some TV - nope.....doesn't work. A text and e mail to the host received no response.
It is perfect for 2 people. The manager at check-in was pleasant and assisted with bags. The unit is CLEAN and the bed is comfortable. The surroundings are lovely and the neighborhood is top rate. Truly a 5-6 star location. The park is across the street - William and Kate are really your neighbors. Tube is 3 blocks away, Whole foods is 2, 24 hour bodega is 1 1/2. 5 star hotel is at the end of the block.
The take home:
Perfect for 2 fit people who are not planning on spending much time in their room. The price is fair and the location is perfect. Think of it as a Super 8 Motel next door to a 5 star resort. All of the benefits with some sacrifices.
