Situated very central (Sol/Plaza Santa Ana) and was perfect for us (2 adults, 3 kids between 4 and 11). 3 min walk to Sol metro. Easy check in/out and a clean and tidy apartment ideal for us. Tiny bit of noise from neighbouring bars but that is to be expected so close to the centre of town. WIFI great, comfortable beds - in all, not a lot more you can ask for. Helios replied very rapidly to all messages.
Would stay again!
