This could be a lovely place to stay with a bit of tlc. It's well laid out and comfortable. We found it conveniently placed for Westcombe Park Station and the places we needed to be in Greenwich. The host was friendly when we spoke on the phone. Though it's near a busy road, there's a great view from the balcony.
The flat would be more welcoming with a really good clean and a few simple touches. eg Some of the bedding was stained, there weren't any bath towels (though they were provided when we asked for them), the washing up sponges looked really grubby etc.
We couldn't get the balcony door to lock.
Better to call the host than message if you want a quick response .
