Not so luxury
The good:
Location was great - 5min walk to Green Park station and even less to the beautiful Green Park. The heating worked well and the water was hot. There was a table I could work at and the small bed was comfortable.
The not so good:
I had to ask questions about address as the info provided was incorrect and wait for a relative to be available to let me in (after check-in time). There was also no left luggage as offered.
There was no printed info, so if you didn't ask or recall from initial meet, it could take a long time for the host to reply to questions such as where to put the rubbish.
The flat needs a good clean, basic maintenance (eg bathroom door couldn't be opened from inside the bathroom if closed, the extractor fan in the kitchen didnt work, some light bulbs had gone and the smoke alarm had been de-activated).
Overall, it is great for location but comes up short on the "luxury" tag.
