We really enjoyed our stay, the apartment was very clean and felt really spacious. We also loved the area and were glad we ended up staying there! Still really easy to get around to see the sites either by taxi/metro/bike etc, but much less touristy than the centre which we appreciated. There are lots of great places to eat and drink we ended up eating nearby each evening and it felt like it would be difficult to find a bad meal!
Something to note for future guests (and maybe I missed it in the description!) but there are some stairs to climb before you get to the lift. Additionally, when you first arrive at the appartment, you need to go up all three flights of stairs to get the keys (incl a key for the lift). This would not normally have been an issue but I had damaged my knee a few days prior. I also asked Andreas whether it would be possible to arrive whilst someone was still at the appartment to retrieve the keys without having to climb the stairs and did not even get a reply which was disappointing - communication was otherwise fine though.
On the last day, the cleaner turned up at 10.20am, although we had told Andreas we would be there until 11am. It felt like they probably needed more time between guests, but in that case, you could just adjust the check-out/check-in times - we would have just been ready to leave earlier and not in the shower / getting dressed when the doorbell rang.
Overall, despite these two small issues, we enjoyed our stay and would definitely recommend to others!
