Nos. 127-137 (odd numbers) Mostyn Street, Llandudno are a row of three-storey buildings with attics. They have slate gabled roofs. The exterior is clad in cement render or pebbledash. The top-floor windows have simple surrounds, while those on the first floor are accentuated by Ionic pilasters and entablatures. Ground-floor shops are present, some with verandas.

The buildings are stepped to follow the uphill gradient. Two box dormers are visible, featuring modern glazing. The second floor has three-light casement windows. The first floor has two splayed bay windows. The ground floor has plate-glass shop fronts, and at the right-hand end is a rusticated round-headed doorway, mirroring the design of No. 129. A three-bay cast-iron veranda, dating to the late 19th or early 20th century, is present. It features columns, two of which are fluted, along with decorative spandrels similar to the veranda of No. 135.
