We haven't stayed in a studio for awhile, but I'm pretty sure there's plenty of room for those items. The refrigerator is built into the base cabinet of the sink, so it's a little bit bigger than the portable rental ones. However, there may be very little freezer space.
We'll be staying in a studio for our next trip, so I'll be interested in hearing other responses as well!
Unless there has been a change, the "freezer" is really just a small shelf area and doesn't keep frozen things very well. Ice cream is likely to melt and you could only fit a pint.
The refrigerator itself is a pretty good size as already described.
Just found a pretty good photo of the frig on Deb Wills site. The comparison to a dishwasher is excellent.
LOL!! When I was trying to find a picture I was thinking, "we've seen pictures of toilets, tubs, beds...I wonder why no one ever took a picture of the inside of the fridge?" Little did I know, you have that covered! Great job.
