I stayed with Marco and Simona for 17 nights. The room was very nice and comfortable with lots of sunlight, and Marco and Simona were very friendly and welcoming. The location is perfect, it being just a 5-10 minute walk to the bustling Portobello Market. The Hammersmith and City line is also 10 minutes by foot and takes you right into the centre. I had a great stay at Portobello Road/Notting Hill, and would definitely recommend it.
