Owners should bring the dog's food as you may have different dogs and each eats a different food. Also, you may not have the time to go buy the food or may not find that brand in your are and will have to order on line. I always discuss what they eat (wet or dry) and how much, during the meet and greet just to have an idea. I make sure they're aware that they need to bring it with them.

When I get a request from a guest, I google the breed + the word temperament. I get a lot of valuable info that way. Some web sites will tell you specifically if a breed isn't suitable for an apartment. These are often hunting dogs that need a lot of physical and mental stimuli to feel tired and sleep while they're home. Be aware that dogs that are high energy and are medium to large size, need more than just several walks a day. They need lots of running, playing ball etc. With a little dog, you can play fetch with him in your living room. With a larger dog, you'll need a back yard so in other words, high energy small dog can be accommodated much more easily in an apartment than a high energy large dog. If a dog is low energy, laid back like an English Bulldog for example, you'll have no problem hosting them in an apartment.
