Salwa is a lovely person with a great apartment. The neighborhood is nice, has convenient access to three tube stations, one of which is Paddington, where the express train for Heathrow departs from.
Salwa had no problem with us asking to arrive around midnight, and had tea, wine, some spare toiletries - basically everything we could ask for after taking the train from Wales. The room even has a mini-fridge!
The peaceful back patio over the yard is a wonderful respite after a long day in London. Great stay!
