i Stayed there for 3 nights last weekend, it was great, the location is central, so easy to get everywhere, the flat is clean, tidy and cosy, it is just as in the pictures.
Ana was helpfull and nice and i could get an early check in.
Maybe the 2 small negative points were that it is not really soundproof, you can hear people in the hallway, bells ringing,.. and that there is no daylight in the "kitchen/livingroom area" but i would definetly recommend it or stay there again
