There are both significant pleasant surprises and unpleasant surprises here.
On the good side, the apartment itself is beautiful. The ceiling is extremely high and the apartment feels very spacious in a way that the photos do not capture. The bed and the couch were extremely comfortable, firm, and high quality, and I slept great! The kitchen also had all the cooking essentials that one could reasonably want.
On the bad side, the internet was unbelievably slow and borderline unusable. This was very important to me, as I was trying to work in the apartment during the pandemic. This made the stay quite painful. The host does not provide timely and thoughtful responses. The check-in process is overly complicated and the host's instructions could use some improvement.
The goods and the bads balance each other out, so all-in-all I can say that my stay was only ok.
