My parents came to visit me and stayed at Tatjana's house. They really loved it! Both Tatjana and her friend are lovely and cared about every small detail for their guests. Although my parents couldn´t understand English, they felt at home and they told me that if they go back to London they will definitely tell me to contact her again.
As for the room, it is very nice, with a very comfortable bed and in a pretty good area.
Thanks a lot, Tatjana!
