Not in Heart of the city, but near Tallin ferry terminal. Nice sights if room is well chosen. For those who arrive with auto notice that their motor vehicle parking lot is 500 m faraway from the hotel and fees 27€ each day further. Cafe Linnankellari operates from the basement https://lakitoimisto-helsinki19633.ampedpages.com/the-2-minute-rule-for-lakitoimisto-helsinki-49037149
