Great, central location, closest U-bahn stations a 3-5 minute walk away. Very friendly hospitality and service. The room itself was nice, clean, and quiet. Without the A/C turned on it was quite hot - which is normal for July. The room also doesn't darken 100% - which was not a problem for me, but might be a problem especially for light sleepers - but again, nothing I can complain about, given that it's July.
Can highly recommend these apartments for either business or personal trips!
