Couple looking for a flat/room from 1 September

We are a couple (31 and 33 y. o) looking for a long-term place to live in Bristol starting 1st September.

We are generally quiet and independent people who value a quiet, homely environment without nightly parties. We are both considerate roommates and respectful of other people's space. However, we don't mind spending time in the evening watching a movie, playing board games, or just chatting.

Ideally, we would like to rent our own apartment, but given our budget, we are also considering a double room with an en-suite bathroom.
