My wife and another couple shared this penthouse for three days in early May.
Mostly, we loved the place. It was ideally located, right in the heart of the old city. The apartment is pretty, airy, and very modern . . . almost straight out of the pages of Architectural Digest. The kitchen and bedrooms are spacious. The views out the windows are awesome.
And Julie and Michael -- though we never met -- were extremely responsive hosts. Check-in was easy, and the few questions we had during our stay were answered back immediately and helpfully (e.g. we couldn't figure out how to make the air conditioning work and it turned out to be because a fuse needed to be turned on). Three flights up was no big deal . . . good exercise . . . and there is a (slow) elevator too, if you want.
Only a few little nits. The kitchen cabinets are way up high and the ladies couldn't reach the coffee mugs. And at least in our room (we stayed in the larger one) there were no reading lights by the bed . . . no way to read at night without the big overhead lights on controlled from switches across the room. Also, my wife didn't like all the fake plants around the place, and that the windows didn't open (a door that leads to a fire escape does let in fresh air, though).
The one really strange thing about the place is that in the larger bedroom, the bathroom is IN THE MIDDLE of the room (well I guess it is sort of over on one side of it). You can see this in the pictures, so we sort of knew about it in advance, but it is even stranger in real life. Obviously you have to kick your partner out of the room if you have to do anything serious there! OTOH it was fun to watch her shower :-)
The other smaller bedroom has a bathroom down the hall that is perfectly normal, but tiny. There is also another full bed in that hallway, if you needed space to sleep anyone else.
