Jay is a wonderful host, very friendly, very helpful, always there for his guests.
The Casa Blanca is located a bit far from the city centre and public transport is not the strongest side of New Orleans. Thus it's the best place for those who drive, otherwise a 12$ taxi ride to/from french quarter will save you :)
However, neighborhood is nice, clean, safe and quiet.
The house is all for guests, there are 3 rooms and some common space. In 2 days we haven't met the other couple living in the second room :)
The place is neat but it doesn't match my personal standards of cleanness, especially bed-lining. I saw reviews saying that the place is clean, and I see for some people it is, but that is not even near to hostel/hotel standards. House is also quite old, although creatively redecorated and repainted, I assume with Jay's bare hands and all love. Still cleaning is a side to improve.
