This is a clean, practical flat in an amazing location (explore this area instead of heading straight to Old Town). Kaspars is really friendly and accommodating.
As the other reviews say, there are A LOT of stairs if you're planning on doing some drinking, and the main gate to the courtyard locks at about 11pm, but press a buzzer and a man eventually appears to let you in.
All in all very highly recommend.
