Is this good value for £130?

Hello all! I'm a newbie gravel cyclist however I'm looking to purchase a "cheap" road bike just to potter around with some friends on. I've seen that the specialized allez is a "beginner" bike to road cycling. Ive stumbled across this advert on the local Facebook market place and was wondering if this is good value for £130?

From digging it appears to be a 2019 spec model. Also I'm 5"11 and I'm stuck between a 56 cm frame and the 58 cm frame... Would anyone be able to advise if I should get the larger size?

Here's the pictures that are attached to the ad!

Thank you for reading and apologies if this is the wrong place to ask!
