We are a family with 2 kids aged 4 and 6, and we stayed for 3 nights in Violeta's flat.
The flat was perfect for us, perfectly clean, very functional, quiet neighbourhood yet close to shops etc. and a short bus ride to the busy part of Portobello street.
Violeta was very arranging for the check in despite our late arrival.
If I really had to make a reproach it would be the lack of proper blinds or shutters for the windows if you are used to sleeping in the dark like us, but that is a general thing in the UK.
