Mark's place was extremely clean, comfortable, and well equipped. There were plenty of towels and spare bedding. The kitchen had all of the necessary tools for cooking and had nice, new appliances. The space was perfect for four people!
Like other reviews mentioned, the ceilings are pretty low. My friends and I are all on the shorter side and didn't feel claustrophobic at all but if you're over 6ft you might be uncomfortable here.
Mark's place is a very quick walk to Tulane University. There are some bars and restaurants in walking distance, as well as the streetcar. Since we went for Mardi Gras and the streetcar wasn't always running, we had to take a lot of Ubers to get to the action (parades and the French quarter). I also noticed that there aren't any supermarkets within walking distance, so keep that in mind if you're planning to grocery shop and cook.
Overall we had a great stay at Mark's place and I would definitely stay here again!
