my stay in Milena apartment was very nice. the room is comfortable, the bathroom not the kind of a ,, luxury" ;) but very clean. ask Milena about alternative way home if you come back late, when the park is closed. there is about 6 stops from Victoria station. if you use public transport and you stay more than 2 days is better to buy oyster card http://www.londonpass.com/?aid=19&gclid=CO_Uosm1qbMCFUFb3godpB0ApA - is much cheaper.
