The house of Simona is very nice. Especially the host, Simona is so kind for everything. I can feel like I was at home because of her hospitality. Also the house is close to the underground, it takes like 15 minutes by walk. There is bus stop right in front of her house. Her coffee was so fantastic and the memorial park near her house is the good point to see the night view of tower bridge and the shard. I strongly recommend to stay her house if you are visiting London.
