This is a really great place! I stayed here for a conference a little outside the city centre and for some sightseeing (almost a week).
It was the perfect location: super central and very close to the subway, but still calm and quiet and away from the touristy business!
The studio-appartment had everything you could wish for or need, including a washing machine, airco, small kitchen with freezer, TV with YouTube and Netflix, and great internet.
Communication was easy and friendly, check-in with key box was convenient. Would definitely recommend, if only for the delightful hallway of the appartment building!
