Suggestions on where to stay in Fort Myers, Fl.

Can you recommend a place to stay in Fort Myers, FL—NOT Fort Myers Beach? I am visiting my grandparent who lives near Fort Myers Shores off of Palm Beach Blvd. I am only finding cheap motels and Comfort Inns when I search online. I would like to be no farther than 20 min. from my grandparent’s house, but I would like to stay somewhere that has a little charm (bed and breakfast, boutique hotel, vacation condo…). Please help me with your local knowledge!
