If you're looking for value, Dublin is the place to go.

The city was ravaged during the eurozone crisis and the real estate market took a nosedive.

"Property is still discounted and could be said to offer good value in the context of strengthening industry and growing employment," said Barnes.

The city is moving to attract young people and technology companies. Google (GOOG) and Facebook (FB) both have large offices in the city.

A two-bedroom apartment typically costs from $210,000 to $560,000.
