Server :: Ssh: Prevent Disconnection After A Command?

I wish to create aliases to log into a server and go to a specific folder. For example, I have two aliases:

Code:

alias REP1='ssh me@server cd /REP1'
alias REP2='ssh me@server cd /REP2'

and of course, I'm disconnected after cd commands. I found no ssh option which prevents this disconnection to occur. I also tried the following trick:

Code:

ssh me@server "cd /REP; bash -i"

but it left me with a crappy shell (no color, directions keys printing ^]]A, ...)
