I don't know if it's exactly what you're looking for, but my mother is an innkeeper at Scarborough Fair in Federal Hill. It's beautiful and safe, and she makes the food, so I can say it's pretty good! They don't have any sleeper sofas (I don't think) but one room can be a king sized bed or two twins.
