Is it ok to leave these dogs this way?

We have been asked to care for a pair of dogs during the Thanksgiving holiday weekend. They are little, Pekingese, they live in an apartment and we are supposed to visit twice a day. During the time we are gone they are confined to the bathroom. We are supposed to take them outside for a potty break, feed them, and let them run around for twenty minutes or so, then it is back to the bathroom until our next visit. The owner left this morning and will be back Tuesday afternoon, so this is the routine for five full days. I don’t really consider myself a dog person, but I feel sorry for these guys because this doesn’t feel right to me. Is the set-up just fine or should they have been kenneled?
