We had a very comfortable stay as a group of 5. The flat was even nicer than the photos, and was very spacious!
The check in process was very simple, and the staff in the office incredibly helpful and friendly. We requested an early check in and were able to from 2pm, which was great as we got in early. We also were able to have a coffee and leave our things in the office before the flat was ready.
There is a convenient tram a very short walk away (2 minutes) but be aware that the metro are about a 15 minute walk.
We had some issues connecting to the internet and whilst we were able to connect eventually through messaging on the app, be aware it may take a little bit to set up.
Overall a great stay, and we would definitely book with sweet inn again!
