Having done the walk with the other half around the environs of the temporary accommodation, it struck me that we are not, in fact, really in Eira, but in its slightly less salubrious neighbour, Ullanlinna.
Still, from googlemaps (apologies for my uselessness on computer – can’t remove that BL logo!), as well as from personal experience, it does seem that Laivurinkatu is at the meeting point of 4 interesting areas: Eira (mansard-rooved architecture at its most gorgeous, many with sea views; embassies, families and such amongst luscious greenery), Ullanlinna (similar only laid out as perimetre blocks rather than quasi villas as in Eira, hence fewer trees but still close to the sea), Punavuori (Red Hill, even a port is by the sea, but unlike the preceding, has had dodgy reputation that preceded even the industrial era, working class until the 1970s, now trendy but saved from ueber-gentrification by small flats and narrowish roads). Towards the west it’s clearly bounded by Tehtaankatu, Factory Street. Then there’s Kaartin Kaupunki and/or the area up to the Observatory hill to the north-east, with more lovely flats and the sense that, despite the odd dead shop-front life still revolves around traditional urban functions in recognisably urban landscapes. Somebody has listed the more “interesting” shops, selling designer goods, on the web, here.
