The good:
location
quiet bedroom for excellent sleeping
thick walls that keep the cold out. I imagine in summer they will keep the place cool. We never needed the heating despite a very windy and cold April.
Things to consider:
it can get loud with the upstairs neighbour stomping around (obviously not the host's fault, but good to know)
low ceilings in the whole flat, esp the bathroom. consider this if you're tall (my bf is 😅)
check-in very quick and smooth, *but* if you use Airbnb as opposed to a hotel to have some sort of exchange with your host/locals, this won't be the place for you -- self check-in means you actually never ever meet your host, it was a first for me, personally. I'm sure some people prefer it this way, just be aware of this when you book :)
Good place for a short stay as it's conveniently located, cosy, clean and very good for resting.
Wouldn't recommend for longer stays as it is rarher small, albeit well equipped with everything one might need, includimg hairdryer, washing machine and iron.
