Excellent place I can recommend for everyone. The host is very helpful and always ready to step in. The apartment is ideally located in a walking distance to pretty much all the sightseeing places. just enough to walk a heathy appetite and see something interesting.
The street sounds might be a bit too loud on the balcony, but you won't notice them inside.
A small note to tall people - if you're over ~185cm high, the bathroom and shower would be a bit of struggle.
Other than that - this is an amazing apartment which I can definitely recommend for a couple.
