The location is just about as perfect as it gets. John was extremely responsive and made us feel very welcome. He helped us get our bearings as we arrived. We had one minor fridge snafu; he replied immediately and we were able to easily and quickly take care of it.
This is a six floor walk-up (so not for someone who has mobility issues or is not in relatively decent shape) but just think of the five flights of stairs as a way to burn off all the yummy meals you’ll eat at any number of great restaurants within just blocks. It’s also not really equipped for cooking (no coffee maker or much for glassware, dishes, etc.) so if you want to make light meals on your own this might not be a good fit.
