From which year are MNNIT Allahabad students given single-seater rooms?

The scenario of hostel room allotment is different for girls and boys at MNNIT. 

Girl students do not get single seater rooms even in their B.Tech final year. Final year girls get two seater rooms.

Now as for boys,

1. Freshers are allotted Swami Vivekananda Hostel, and each room contains 3 people. It is a newly constructed 7 floor hostel building. The rooms are nice, except for the lack of LAN connection and below average mess food. The in-time is 8:30 pm.
2. During the second year, one has a choice. Either one can choose the senior hostel complexes- Patel Hostel / Tilak Hostel, or opt for Tagore Hostel. The earlier two have 2 seater rooms, while Tagore is 4 seater. Tagore Hostel is exclusively made for second year students, and it is spacious. But it is far from the college campus, so one has to walk a lot for the whole year. Patel and Tilak are old hostels, and inhabited by senior students as well. 
3. In third year, one gets a hostel from among the four senior hostels- Patel, Tilak, Tandon and Malviya. The rooms are two seaters, but there is a single LAN port in the rooms, so wifi sharing is predominant.
4. During fourth year, one is allotted a hostel among the four senior hostels. But as a final year student, one gets a single room. 

This is the complete detail regarding room allotment for hostellers at MNNIT Allahabad.
