Moldy apartments are the worst.
I just moved out of an apartment myself that wasn't moldy but suffocating me nevertheless and I slept poorly there for almost a year, due to noise and an unhealthy indoor climate. Just moved house again ( see my latest post ) or am actually still in the process, for the umptieth time in the last 5 to 6 years, as I don't like to stay stuck and keep following my intuition.
Hope to own a seaside apartment myself, one day, but for now the Portuguese countryside will have to make do ;^)
The Portuguese countryside doesn't sound so bad, although potentially a bit chilly this time of year?
I counted that I've moved 12 times in 7 years, probably discounting a few moves/short stays with friends. It's tiring, but if you aren't settled and can do it, why not? :)
