Hungary has beautiful lakes and forests where you can buy a house or even a castle for renovation at the same price you would pay for an apartment other places, but you will find there is mighty little there, and outside the capital you might encounter language difficulties and start to get a little depressed at the long winters. The phone system is modern, efficient and mostly digital. Although international calling is relatively expensive, increased competition will drive this down in the next year or two. The mobile phone penetration rate is very high. Hungary has two GSM networks and a third being built, with calling costs being low by mobile standards.
Internet access is excellent and cheap.
The postal system is adequate and improving. It works, but international mail costs Western European rates but without the speed and service to match. Anything urgent should be couriered. Of course there is an airport, with direct flights worldwide. You can also reach Budapest by train, including overnight direct trains from Paris and Brussels.
