As for costs we need to remember that for many if not most travel will be the largest part of the bill, and when you include the cost of getting there London becomes one of our cheapest potential venues
Lets remember that London isn't alone in that. If the Wikimania is Europe - does not mind if is in Portugal, Spain, France, Italy Germany, Poland or the european part of Russia - the travel cost will be as cheap for other European residents.
However, for people attending from outside Europe, London is a lot cheaper than most places to get to due to being a major hub. To get to a lot of places in Europe from outside Europe, your cheapest route is often to go via London. (Paris and Frankfurt are also major hubs, but the other countries you mention would generally be more expensive to get to.)
