The penthouse is a really beatiful apartment. There is easily enough space for 4 people. It's like a pre-made apartment (it is really nicely furnished). You'll find pretty much anything you need already in the apartment (Kitchen equipment, living room, 2 bathrooms, heaters, tv, etc).
The location is perfect for an apartment like that. Its quite, yet easily accessible (bus, taxi, by foot). The view is pretty amazing as well, as the aparment is located on the top floor.
Check-In and Check-Out was amazingly easy as well, as it was simple to communicate with Michael.
Finally, the price was just unbealievably fair!
I highly recommend giving this offer a try!
