Brandenburger Tor

German grammar, 5 stars question!?
1. (in)__ Pension Mai übernachten
2. (unter) ___ Brandenburger Tor verabredet sein
(and what do these sentences mean? I can’t translate it)
3. Manchmal machen wir “in” Grunewald auch einen Spaziergang oder eine Radtour.
the “in” is right? I don’t know whether it’s “in” or “in dem”?
Thanks so much in advance
1 der (to spend the night in the pension “Mai”)
2 dem (to have arranged to meet under the Brandenburg Gate)
3 in (Grunewald is part of a city, so you only need “in”)
Edit: Wait, which Grunewald do you mean now? The actual forest or the Berlin district?
district = in
forest = im
