We stayed at Royal Courtyard in March 2018. It is a wonderful B&B, with a real good breakfast, that allows you to save time and money (though there are great neighborhood coffee places too). You get a real taste of 1850 New Orleans - high ceilings, bright rooms, interesting furniture, etc. The host, Diana, was very helpful and accommodating. The property is under a new management, our guess is there will be more pleasant changes withing a year. The weather was still a bit chilly, so we could not take a full advantage of the courtyard in the back, but it should be a great place to cool off or to enjoy the morning.
Keep in mind it has a feel of B&B, you are sharing the house with other people - we loved it, but if you are looking for an apartment , it maybe not for you.
It is not the cheapest option around, but consider both the location (you are 5 minutes walking from Frenchman St) and the cost of breakfast - it was worthwhile for us.
