We spent a couple of nights at Mónica's place with our two young children. The flat is cosy, nicely located and well equipped. The beds are fairly comfortable, although in the summer months it can get a bit noisy at night because of the busy Terrazas downstairs.
There's a lift, but the entrance to the building is not step free. Overall, it works, but it's probably better suited for families with older kids or no kids whatsoever.
