The location of the flat is great but describing it as a “designer studio” is a bit much. Sure, someone’s designed things but it’s pretty basic. I really think the flat needs a good renovation to be suitable and competitive. My personal feeling would be get rid of the kitchen and make it a shower room. As many others have said, the toilet/shower scenario is a challenge for two people. As a 6’2” person I found using this room a challenge.
The room was cool during our stay when outside temperatures were low 20s, but there was a drain smell from the shower that came and went.
