Basic Czech phrases for tourism?
I have almost 20 days (less than one hour per day) to learn some basic phrases in Czech which need to be useful for tourism. Do you know any good source where I can learn them?
I've been doing some lessons on Duo, but does it worth the time? I don't know if the sentences on the lessons will help me :/
Thanks in advance (and sorry about my English, feel free to correct me :D )
