Still a must go in the UK. Do book in advance, free entry, but quite essential. Go 15 mins before booking time to queue up. Mask not required inside. The national gallery provides lots of hand sanitizer and toilets are well equipped to handle. Currently it's fairly empty inside so you will have quite a privacy and silence you always want in a museum. Go see it now!
