We are considering this as well. You should have no issue getting $1500 for the 4 days, especially in that location. A quick check of Kayak this morning shows that even Motel 8 is charing $250 a night, so $375/night for the whole house should be attainable. I did read that last time, people were charging silly amounts like $5000 a night, but I don’t think anyone actually got those amounts. We are debating trying to rent our Petworth Rowhouse out, and we are hoping for somewhere north of $1500 for the four days.
Looking into just renting a room is a reasonable option as well. I am sure we could get $600+ for 4 nights or so.
