I'll be spending 24 hours mid September in Frankfurt on my way to Barcelona. Im a solo female traveler in my 30s, Looking for recommendations and some questions since I've never been:
1) Hotel vs hostel vs airbnb? What area would you recommend staying in? Ideally easy access to the airport
2) What would you go see in 24 hours? I'll be arriving at 1:30pm and out 4pm following day. I enjoy walking around exploring neighborhoods, architecture, local markets or shops. Im not big into museums unless its a must see.
3) Is it fairly safe?
4) Is eating gluten free challenging?
Thanks
