Maria had an outlet to USB converter that was already in my room which was very thoughtful since I forgot about the power outlet differences--I was able to charge my phone because of it. She was also flexible and communicative with my check-in time due to when my flight arrived, and I really appreciated that since I knew it would take time to get from Heathrow to her place. The location is great and in a safe neighborhood, and there's a nearby street (maybe 10-15min walk) with a bunch of restaurants.
