I stayed in this lovely, very well located, apartment for 1,5 months, and it seems the apartment is not made for that. The kitchen is sparsely equipped (one knife, no garbage bin), no cleaning materials (besides a vacuum cleaner) and no extra set of linen or towels (so changing sheets required some planning at the laundromat). However, the bed is super comfy and the shower really nice.
So would not recommend for a longer stay than a weekend, but for a (long) weekend it's a great place in a really good location!
