I had a great time at Vonnie and Nick's place, from November 28th to December 4th. The room was very clean, with fresh flowers and great luminosity (with blinds for the night). The bed is confortable, the view is beautiful. Even with a colder weather outside, the temperature in the flat was nice and cozy. It is located near Notting Hill Gate underground which is a very useful station - with access to three different lines - to get around easily in the city. There are also plenty of cafés, pubs, restaurants and grocery stores nearby, as well as the Portobello market (a 3 minute-walk).
Vonnie and Nick are very kind and attentive hosts. Arrival: they were flexible on the time I could get there, and all indications were clear, I had no problem finding the place and having a post-flight rest! Stay: always give good advice and are very friendly. They make yourself feel at home (with complete access to the kitchen). Departure: helpful for the morning schedule so I had no problem leaving on time.
Would definitely recommand for anyone wanting to stay in a strategic yet relatively quiet place to explore London. Excellent quality/price. Thanks guys!
