Mar was a fantastic host, super friendly and professional. The place was fairly small but fairly luxurious, with a stylish marble bathroom, top of the line appliances, and panoramic views of most of London's skyline from the Cherkin to the Shard. Clean, but not sparkling. Comfortable with good AC and shower power, but bed too soft for me. The location is great for traveling to tourist attractions, but the immediate surrounding area is boring and soulless. Sound isolation was insanely good: never heard anything from the neighbors and despite being on a major intersection, 10 meters from an underground entrance, the outside noise from traffic or people wasn't a problem either (at least during the lockdown, might get rowdy when nightlife restarts).
