I will be as fair as possible so future guests can get a picture of Mark and Sara's place.
Pros: House. The entire house has 3 units. The entire house is beautiful and well maintained.
Pros: Neighborhood. New Orleans has few nice neighborhoods. The unit is located in a very nice block with nice architecture and steps to City Park. You can go to the French Quarter (if you dare) walking 20 - 25 mins or 10 mins bike. There are several services within walking distance and Esplanade avenue, which is one of the few places where you may want to walk in New Orleans, is also nearby. Finally, the block is amazingly quiet at night.
Pros: the hosts are nice and concerned about you.
Pros: the unit has a comfortable area for 2 people.
Cons: the unit is very dark. We called it "the cave". Nothing too bad if you are staying for a couple of days.
Cons: the bathroom does not have an extractor and the window can barely be opened. Its condition could be improved.
Cons: the bed/mattress is bad to very bad.
Cons: kitchen poorly prepared. No glasses (only plastic cups), no extractor, a single knife to cook, few pots, and the top of the refrigerator was covered with fat (the only seriously uncleaned spot). The table could be refurbished or replaced.
Cons: silent at night but noisy on Saturday early mornings (contractors) and afternoons (neighbor's kids; not the host fault at all but forget about naps). The walls of the unit are thin so you will clearly hear anyone on the unit above or next to you (but this was for really short time frames during the day and never after 10 pm).
Cons: the street is in poor condition, but this is New Orleans so this is everywhere...
Fair: also keep in mind the unit does not have a toaster, washing machine, drier, dishwasher, This is your responsibility because the place is advertised as such. The kitchen had a microwave but there is nowhere to place it. We used a wood box (it is supposed not to have a microwave, so having one was good).
Conclusion: the place is ok for a couple of days.
