Favorite hotels in SF? I’m going in the fall (have never been!) so am looking for a great place to stay but also any other great recs too!

Anyone know of a good spot to send off for a Contax G2 repair?

I’m going to Budapest for the first time this winter! Looking for all recommendations (besides hotel, I’ve covered that!) interesting architecture, must sees/dos in general, hole in the wall type spots, anything off the beaten path
