Our stay at the apartment was great. There was excellent communication with the hosts from the very beginning and arrangements were easily made on our arriving and departing day. The appartment is very well equiped with anything one should need for a short or long visit in London. All the details are very well thought of (decoration, cleanliness, kitchen supplies, bathroom supplies, towels, bed linen, touristic information, etc). We were five, travelling with a 2 year old girl and the flat was perfect for us. I slept on the coach in the living room and it was really comfortable. and it easily became a bedroom at night as it is separate from the kitchen and distribution hall. The curtains in the living room are similar to black out which was great for us.
The flat is very well located, really near to the train station which is included in the travel card of main zones in London. There is also a bus that goes to the city centre which has a lovely itinerary and it's only 20 mins away from the big ben. I recommend using it at least once!
The neighbourhood is quiet and beautiful. And the hosts really kind and helpful at all times on every matter. Wifi was perfect as well. All in all, I recommend this apartment and will definitively go back if I ever visit London again!
