Very disappointing
"Jules" does not exist, at least, you will never speak to him- neither before nor during your stay. The owner has given the property to a 3rd party agency called Houst (they manage 5000 units in London and 30K worldwide). I read the positive reviews and was excited to stay here- indeed the space itself is unusual and charming. However, if you encounter a problem and try to contact "the host", you will be calling / messaging a call centre of customer support staff, none of whom know you, the property or have ever been there.
You might get lucky and encounter no problems, as some other customers clearly were; but for us this was not the case- the heating was not working. I called and messaged numerous times, they eventually sent someone to try and fix it- he was just a handyman, he failed to resolve the problem and admitted it required a plumber; no plumber ever came and we were 4 nights sleeping in the cold, with 2 young children (4 and 2), in October. Plus the TV satellite box did not work- this was also ignored and not fixed.
It ruined our whole stay as it was during a storm ('storm Alex') so we couldn't be outside or inside! Plus, they charge £125 for cleaning, which is stupidly inflated and about 3 times what they actually pay the cleaner (its just one girl - we met her)- again, the behaviour of a middle-man agency, not the owner. So be aware, you might get lucky and have no problems at all, but you might not...
