Crack repair/repointing?

Spotted a small crack between a sun lounge (the one with pebbles and brown wood soffit) and neighbours' wall:



What's best way to seal this gap? Would something like a sikaflex work?

Yes most outdoor silicone will fix that

Does the sun lounge belong to the neighbour?

No, that's us.

I am guessing something like https://www.screwfix.com/p/no-nonsense-builders-silicone-grey-310ml/912gr should suffice and I think the gap isn't large enough to require a backing rod.

I would spend a little extra and buy a hybrid sealant, rather than silicone. 
It will age better and not need renewing in a few years.
Something like Sika EBT or even CT1.
Placing in a bucket of warm water for a few minutes before use will make application much easier.
