Unfortunately the electronic key was broken and it took hours to get access although a caretaker tried. We had to photograph the key, assure them we didn't break it and wait till their only replacement arrived. Perhaps not the welcome we had hoped for.
The apartment is tiny and although there are interesting design features, parts aren't maintained or finished.The cleaner had left all the washing in the machine so we had to empty it before we could do ours. We did appreciate the cleaner bringing another key to us.
