I've been living with Antonia for 3 months and I had a great time. The welcome was warm and friendly and I immediately felt at home. The flat is exactly like the pictures and the blue room is a nice and cozy room to relax after a long day working and running around the city.
Antonia is a perfect host and a great person to stay with. She is very helpful and you can also have a nice chat with her in the cozy living room (studio).
The flat is 4 min away from the tube station and it takes you about 15 min to reach the city centre. I always felt safe, even while walking home at night (after 11 pm).
I can highly recommend staying with her and her two adorable dogs.
