No more here, according to their site (https://iserviss.lv/lv/Kontakti) they are now located at Kr. Barona iela 70. And there is no vacant place - I.e. point to be removed from map completely. They only possible place where they can be located in the past is some shady door between Maxima and Natush. It's closed and not transparent, from the markings - it leads to some offices upstairs. Non of them are iserviss.
