I don't know what actual cause was, but it was a problem that existed when we moved in, we were told it was the the pointing and they would fix it when it was dry (they didn't) . We've moved into our own place now so it's not something I'm worrying about, but what I do know is that dehumidifier is incredible at removing moisture.
Definitely get a dehumidifier, we've got one of these https://www.amazon.co.uk/Meaco-Portable-Compact-Dehumidifier-DD8L/dp/B007X236NQ
It's a bit spenny but it's excellent, we were mainly using it for drying clothes but the last place we rented had a problem with the pointing and the bedroom walls were damp and moldy, we blasted that on and the walls were pretty much dry after about 3 days.
