This spacious apartment is arranged over 259 sq m / 2,788 sq ft and located on the fourth floor with an open aspect to the front over Devonshire Place and partial views over Regent's Park to the rear. The current owners have modified the layout by opening the two rear bedrooms to create a large master bedroom suite with open dressing area and ensuite bathroom but can easily be re-instated as two bedrooms - providing 4 bedrooms in total. The three, south facing reception rooms are across the front, benefit from high ceilings and are ideal for entertaining.
