We enjoyed our stay in Berlin but there were a few things we thought we should mention that may help others.
All this has been communicated to the hosts and they were very accomodating.
The listing states a king bed and
although it may be the same size frame it is actually two single mattresses together with two seperate covers.
The apartment is also a lot noisier then
we had expected from the listing.
There is the noise from the
train but that isn't too bothersome, it's
more the wooden stairs right next to
the bedroom and the street outside.
We were awoken a few times during the night not only by cars and trucks driving past but also people talking and even just walking along the footpath, we could even hear traffic at the intersection down the road.
The heaters didn’t seem to warm up the large space enough for us, even on level 3 or 4 they didn’t feel like they were warm enough.
The wifi blocked us from a few normal websites.
