Sorry for not responding sooner - I've been on holiday. This restaurant actually has a website with an English language option. On it, it states that it is open Wednesday-Sunday, from 1pm till 10pm.
There are no details about it closing for holidays, but there is the option, if you want to make sure, of phoning them on (+34) 922 768486. They have an email option, too, but this doesn't seem to be working.
This looks like a really nice restaurant. I hope your visit can go ahead as planned.
