The place is excellent! It is an underground museum with a lot of old toys and cartoon characters from 80s-90s. There's also a kid playground with vintage stuffs (like old stove, pans and utensils). There're also old arcade game machines and old joystick games for playing like pac-man, etc. On weekday, it is a quite place with not much people. So if you are a solo, this place is highly recommend to visit with your own pace of observation! The place is very easy to get there, normally a bus from T-centralen, did not see much about the parking. Since it is an underground museum, there's no internet signal there but free WI-FI is provided without any log-in needed (and also fast enough). The price is reasonable but a bit pricey compared to the experience gained, the ticket can be bought both online and at the counter, no specific recommendation about buying tickets.
