My partner and I stayed here for a week and, on the whole, it was great! Sarah is a great host!
The room itself is exactly as shown. It is a built room though, with no door (it is a curtain), so keep that in mind. The house looks great from the outside and is conveniently located close enough by public transport (or even on foot) to the downtown-core and French Quarter. That being said, the neighbourhood itself might not be the best if you are travelling alone or looking to go out at night. As friendly as locals are, saying hello to all passersby, there are a few sketchy characters that wait until one is alone to intimidate them, be it during the day or night. If you are not someone with street smarts who is comfortable handling situations where you might get intimidated, stay closer to the tourist epicentre (i.e. the French Quarter). Also, keep in mind that in New Orleans an area might feel very safe then a block later can change completely and vice-versa.
All in all, I do suggest Sarah's place as the location, price and experience of living like a local are well worth it!
