Alberto was helpful, friendly, and talkative. He speaks many languages and was very attentive. He was nice to our kids also, and even gave them gifts!
This apartment is in a great location with some nice cafés and groceries nearby. We walked to Notre Dame and used the two close subway stations.
The apartment was small (especially the bathroom!) but it accommodated the 4 of us just fine for a few days. We were grateful for the air conditioning!
One thing we wish we had known beforehand is that there are windows between the bedrooms, so your kids on the top bunk would have a nice view of mommy and daddy's bed - be forewarned ;)
The stairs to the apartment are old and smell musty, but the unit itself smells nice, is newly (though somewhat sparsely) furnished and inviting.
I would definitely recommend Alberto's place for short stays in Paris!
