My girlfriend and me stayed at Vesna's for a weekend.
Our stay was pleasing, with Vesna giving us easy options for check-in and with a smooth communication and fast answering. Vesna was a great host who made us feel very welcome and who handles her rooms in airbnb very professionally. Bread, cereals, coffee, milk, tea.. available in the morning for a nice breakfast. The house was very clean, which is always a plus.
Location-wise the house isn't in the center of London but it literally takes 20-25 minutes from West Acton underground stop to the city center. It runs the central line, which is available 24h during the weekends, so overall it's very convenient.
Would definitely recommend and stay again. Cheers Vesna!
