If you have the opportunity to take a flat/apartment on the ground floor, or something with an elevator, do it. Unless it’s a very big apartment, you’ll then need to climb up and down stairs every time you want to go outside... and trust me you will want to.
It makes it hard however because stairs can be difficult. If you have to take a flat in the upper level, you will be okay but you’re making the next few months less comfortable for yourself. But, you will be able to come/go.
My first trip to my apartment was on a stretcher, and I didn’t leave for about 2-3 weeks.
