Karen's place is an excellent choice if you want to be right in the middle of everything but on a high enough floor you don't have to deal with noise! The location is superb and you can walk out the door to what feels like an endless amount of cafe's, restaurants and shops! The apartment is very clean and comfortable and our family of 4 felt it was very roomy and cozy. The benefit of being on a high floor outweighs any concern with climbing the stairs as long as you are mobile you wont have any issues! We were very pleased with everything about our stay. We had one issue with the heat and as soon as we alerted them it was immediately resolved. Communication is excellent as well and they were very available for any questions we had. Check-in was a breeze and the manual they provide basically answers any questions you could potentially have about the flat. We highly recommend this place and look forward to coming back to visit again soon!
