Katja's place was very modern and lovely. She provided all the necessities and the bedrooms were very cosy. She wasn't able to be there for check-in/check-out but she left very clear instructions and was easily accessible by messaging. One of my favorite things about her place is that there is a bus stop right outside of her building and it takes you right into central London. It was very convenient and made it super easy and quick to go out and see the attractions. The only downside was that I wasn't expecting so many stairs. Beware if you're coming with heavy luggage. Overall, we had a great time and highly recommend this place to others planning a family trip.
