Our stay overall was great! Adélaide always answered quickly and friendly, and checking in at 23:00 was no problem. Quiet neighbourhood with supermarkets, Metro station, boulangeries and restaurants in walking distance (can highly recommend Pizzeria Luigi Pepone next to the Metro station and Boulangerie Aurélia + side note, not in the neighbourhood - Sold Out Burger was also amazing!)
The bedroom was a little smaller than expected, but definitely sufficient, and it was pretty cold when we arrived, but warmed up until the next day after turning on the heaters.
Maybe a German problem, but remember to buy/bring drinking water, as the tap water has a lot of chlorine and lime/chalk. This showed on the appliances, but overall it was very clean and we felt right at home.
We were two people and only stayed two nights, didn't use the kitchen and didn't spend a lot of time in the apartment, but nonetheless felt very comfortable. Highly recommend, thank you!
