He's pretty easy to fight in melee. All his physical attacks are 100% blockable, and there's usually enough time to get 1-3 hits in between them or drink a bit of Estus. You won't lose as long as you don't get greedy and always make sure you've got around half your stamina available to block. Highly recommend a stamina boosting item (or a combination of two, since they stack) so that you can quickly recover stamina after blocking/attacking. Fire resist ring works well here in combination with a high resist armor such as upgraded Wanderer's/Pyromancer's. If you don't have the time or inclination to upgrade anything, gold-hemmed set is a good choice. Rolling speed isn't important. You can block your way to victory.
