Me and my partner stayed at Carlos & Stig's place for a long weekend break. Both the accommodation and the hosts were superb and faultless. Carlos met us at the accommodation (and was very flexible about check-in times for us). The flat itself is very homely and simple. Not cluttered, felt spacious and yet had everything you needed. The location is unbeatable, in that it's near many points of interest & public transport.
Regarding the shower, we're not sure if it was us doing it wrong, but we struggled to attach the shower head to the stand, so we had to hold the shower head in the end. However, the shower itself is very good.
Overall, we can't fault the place and would highly recommend to anyone!
