★★★★★ First Time User
Oh how I wish I found this app earlier.
Booking is so easy in English, and I had such problems trying to do this previously at rail stations.
Duh! I’m amazed.…
★★★★★ 🔥🔥🔥
This app is amazing. Can’t recommend it enough…
Top negative
★☆☆☆☆ Overpriced. Do not use!!!
Train tickets in this app are overpriced by 100%. Do not fall for it. Use Omio.…
★☆☆☆☆ High fees, no tickets
Fees are high-double the actual train ticket and they only search for your ticket after you select and purchase. Will not use again.…
