My husband and I stayed for 3 nights in January at Proma's. She left us a message 3 days in advance describing in great detail on how to get to her place down to the colour of the front door! She was super accomodating, took the trouble to meet us at the train station and pass the house keys since we were arriving from Manchester by train.
The room was warm and cozy with toilet/bathroom just next to it. We had good night sleep after a long day exploring London as it was very quiet at night. She was very kind to let us use the washer/dryer which was precious as we packed light for our Europe trip.
The place was very accessible with bus stop just in front of the building and a couple more just around the corner, thus it's very easy to get by bus to/from any direction. The Westbourne Park underground station is less than 5 minutes walk and it can get you to Central London in under 30 minutes and Heathrow Airport in an hour.
Our London trip was made easy and memorable thanks to Proma. We definitely recommend staying at Proma's. Thanks again Proma!
