We had a great time staying at Gwenyth's place. The flat is very modern and tastefully decorated. The view is good, the flat has an excellent AC/heating system, and is exceptionally clean. Gwenyth communicated quickly and clearly whenever we sent her a message.
The only real downside is that the lifts in the building make a very loud noise to announce their arrival, so expect to hear them in action throughout the day.
That said, we do not hesitate to recommend this cosy flat to anyone looking to spend some time in the city.
