No flexibility at all by the host.
Asked for earlier checkIn than the usual 3pm but was told it was not possible, at checkout asked for the possibility to leave luggage later than 10am CheckOut time, response was that there was a charge of 30 £ (to be paid cash) for staying up to 2pm, when in the morning I told that I would need the extension only up to 11.30am I was told that the 30 £ where to be paid fully anyway.
To add:
1) on arrival hot water was not available, the problem was solved within two hours by a technician that came very soon (anyway I think that, as a host, you should do basic check before guests arrive not wait for them to call);
2) wifi works well only in the lounge/kitchen... difficult to reach in the two bedrooms;
3) the curtains in the two bedrooms can be considered nonexistent in terms of shading light so, in this period, you wake up at 5 in the morning thinking it is noon;
Asfor location, it is fine as it is close to Earls Court Piccadilly and District lines...
