I have passed through Slovakia several times on European backpacking adventures. I usually end up in Bratislava if Iām in Central Europe.

While there is a variety of ways to avoid additional fees while traveling - I have personally found the Charles Schwab Investor Checking to be one of the easiest and most straightforward accounts to utilize on the road.
