I know this has been covered before but due to various circumstances I haven't been able to do a proper search.

My partner has just spent several days in a Berlin hospital with two broken ribs. We hope to be able to fly back to London on Sunday (BA of course) but will need road transport back to South London. Which is the best company to use? I think a tall vehicle will be best as it will be easier for him to get in and out of. Can we stipulate the type of car that picks us up? Many thanks.
