Romanian here. 5mbps cannot be chosen, not even for rural areas where fiber is being upgraded for free (e.g. the rural town of my parents was upgraded to fiber).

Lowest I know is from UPC which still has some weird 50mbps option but compare that to the biggest ISP, RDS, which has practically made 300mbps the default as you pay the same amount for 100mbps as for 300mbps since a year or so, both for 7$. And by 300mpbs I mean 300mpbs (the remote servers being the bottlenecks while good ones & tests max out).

A lot of things are wrong in Romania but internet is not one of them :) but for those interested, /u/HoliGigi's explanation: https://np.reddit.com/r/europe/comments/2ct58s/average_inter...
