Stayed at Lamington Serviced Apartment for a period of two weeks. We were a family of four so booked a two bed room apartment with one bathroom. The flat is quite roomy in terms of size from London standards, with a nice lounge and fully functional kitchen with all required appliances.
The flat is slightly dated however maintained and bathroom requires maintenance however overall it is nice place to stay for long duration in London.
The staff at reception is very helpful and responsive, cleaning is done once a week, while two tube stations (Hammersmith and Gold Hawk) are in walking distance along with various restaurants, fitness first, pubs, shopping centres and all required amenities.
I would definitely recommend Lamington Service Apartment for a family stay of more than a week in London.
