There are quite a few Poles in Reykjavik. There’s a general feeling that they are not evenly distributed along the city. Looking up my first name in the Icelandic Phone Book one can see that most live in the centre (post codes 101 and 105) as well as in the Breiðholt district. Interestingly enough, there a whole neighbourhoods, most notably Grafarvogur and Fossvogur with no Pawels listed.
Pawel is in fact a very convenient name to choose for this purpose, since it is one of the most common names as well as being unique to the Polish language.
