Me and my mother just stayed 10 days in The Smallest House In The Village, and highly recommend it ! This is probably the best place you can find in East Village (which was our favorite district in Manhattan) !
The house is small, but that is absolutely not a problem for two people (can fit for 3 or 4 people since you'll probably be here just for sleep). The bathroom is great, the bathtube is huge and there is a REAL shower with perfect water pressure. As said in previous comments, don't forget to pull under the tap to activate the showerhead.
We didn't use the kitchen at all, except for the coffee machine. The ladder is a bit tough, but okay for people in a good shape. The bed is very comfortable. If you need darkness when sleeping, you should bring a sleeping mask with you, since there is no curtains for the skylights windows.
We really loved the garden, it is really enjoyable to have a yard in the middle of Manhattan ! (Also, we left two blankets from the plane in the closet, to cover the couch and chairs oustide). Just be careful to let the backdoor open when you are in the yard.
The cleaning person came in the middle of our stay, which was very pleasant.
The Wi-Fi works very well in the garden. Otherwise you can try near the window next to the bed.
The neighbourhood is just perfect : there are so many restaurants, it is so hard to make a choice ! There are all the convenient stores a few steps away.
The subway is close, like 5 minutes walk. Soho, the best district for shopping is 10 to 15 minutes walk.
Olivia is a great host who will answer all your questions.
We won't hesisate to come back in The Smallest House In The Village :) Such a charming place ! Thank you so much Olivia !
