We stayed at Oliver's place for 19 days. The apartment is bright and comfortable. Oliver wasn't in town so we had a very brief introductory by his friend and had to navigate around the house by ourselves, thus communication sometimes could be a bit delayed or unclear.
The lighting of the house is very good, but because there's no black out blinds in any of the bedrooms, all of us (including the toddlers) could only sleep when it's dark outside (10:30pm-5am)
The design of apartment is very modern, but the stairs are quite dangerous if there are babies or toddlers around.
The kitchen was very well equipped, the location is quite good with supermarket within walking distance.
Overall, it was a satisfactory stay despite a few hiccups with communication.
