Stayed in Congress Avenue Hotel during a short visit to Vilnius and the location was just perfect, on the main avenue and in a short walking distance to all main attractions.
The room was very big and spacious, big windows, comfortable beds, great bath-room. Only downside was not very good smell from the bathroom (keep the bathroom door close)
Very nice & welcoming staff, don’t lose the room plastic key - we’ve been told that it’s extra 5€
