I stayed there 5 days with 4 friends of mine in December.
The apartment is big enough for 5 persons, clean and comfortable.
There's only one bathroom but the shower and the washbasin are separated from the "toilet", so you can use them at the same time!!
The weather was not very cold outside, but the apartment was warm.
The location is perfect: you can walk to almost all touristic attractions, and the subway is very close too!
Dan has an original and very useful way to give you the keys!!!
I recommend :-)
