We loved staying at this apartment, it was great! You can access every door with an app, so it's really safe and practical.
We asked them for bed sheet changes one day and they brought us new ones that evening.
If I had to point some “negative” minor issues, I'd say the lighting in the kitchen is not great, the shampoo left is terrible (girls) so you might want to bring your own, and there is not much space left for clothes. If you're staying for 2-5 days it's fine.
All in all, we loved it!
