We were a party of 5 (3 adults, a 3 year old, and a 6 week old) and this space suited our needs perfectly, giving us enough space to enjoy our privacy while also maintaining an intimate feel.
It’s easily the most spacious and airy basement I’ve ever been in, but you do need to keep in mind that it’s a basement, so natural light is scarce. It didn’t bother us because we spent more time sightseeing and eating than we did at “home,” but I can see others being affected by it. And since it’s below another short term rental, the extent to which you hear stomping or pitter-pattering of footsteps above is going to be dependent on those upstairs guests and completely outside of your control. We got pretty lucky in that it was a family with a some kids who would periodically and joyfully prance around (without malice), and we just considered it a tradeoff for if and when our 6 month old cried during the overnight hours. But YMMV.
There was just enough kitchen space (and kitchen utensils) to support our needs, though you should probably be aware that there’s a counter and not a table, so it’s not likely that more than 2-3 people will ever be able to gather around and share a meal together. I consider that a fun quirk and a reasonably efficient use of space.
The shower was great. I told friends that the shower head was clearly set to “You’re not in California anymore” mode; prepare to be blown away by water pressure and volume. And in that same bathroom is a washer and dryer to support your laundry demands during a longer stay (or, if you’ve got two kids under 4, your constant laundry demands).
Street parking sounded like it might have been a problem based on the check-in instructions, but we never had an issue with it; parking was always plentiful.
In general, this is a surprisingly comfortable and surprisingly spacious basement level apartment in what we found to be a super convenient neighborhood.
