 The only issue I would comment on is my room was on the Ladbroke Grove side the traffic could often be noisey first thing in the morning This is not the hotels fault but it could be an issue if you are a light sleeper 
 The hotel is close to Portobello Road and is also close to good public transport to get you to most areas and to Paddington for the express to Heathrow As a solo traveller I felt safe at Portobello House the room was clean modern and room service from the bar downstairs was very convenient
