We stayed with a group of 8 at the apartment. The location is really central close to the national museum. Basically all places of interest can be reached by foot easily. The apartment itself is furnished in a very modern fashion and was clean. The view from the balcony is really awesome, and one of the highlights. Would stay there again. Check-In and out was smooth and easy.
Some things to note, which might be important for some groups:
-	There is only one full-sized shower in the apartment (the rest are bathtubs with shower heads).
-	Parties are definitely not welcome here, there are signs everywhere warning about noise complaints etc. We were sitting outside at night enjoying the view and having conversations, which was not a problem.
-	There is only one (rather small) parking spot available. If you have a larger car (bigger than e.g. a BMW 3-series), you want to make sure to check with Vesna first. We had a second car which we parked at a local public garage (MrParkit) which is just 5 min walk away.
-	Interior design includes some erotic art pictures
If these points don’t apply to you, I would recommend the apartment.
