The description is pretty accurate. It's not as small or cramped as you might think. We were two people and never in each other's way.
Note that Uber cannot get to the house due to restrictions on the streets, but taxis can. We walked up the hill from the metro stop with our bags with no regrets so that's a viable option too.
Wish we had had more time to walk around and soak up the neighborhood; it's a little maze of narrow streets.
