The cheapest option for students is Svehlova Student Dorm (in Czech Kolej Svehlova) of the Charles University. It is about 14 minutes by walk + 6 minutes by tram from the Marriott. The rooms are all single rooms, very large, with internet (you need to bring your ethernet cable), no air conditioning. Shared bathrooms+toilets are in the hallway (shared also by local students staying at the dorms). The building is built in the Art Deco style and is quite charming from the outside. From the inside, the building and the rooms are worn out and in need of renovation. Do not expect the staff to speak English, but you can ask local students who live at the dorms for help/translation. To get some taste for the Czech language, see a text on architectural history of the building. There is no breakfast at the dorms.
