Frankie Says is a very effective team : responsive, fast and accommodating ( thank you again for the extra hour for the check out and reference to your partner for luggage storage). Everything is handled remotely but smoothly.
Location is great : quiet area ( we stayed 4 days and had no issue with the noise at all) with a fantastic little restaurant across the street. top coffee places around the corner and walking distance to London cultural, shopping, entertaining, tourist spots.
Flat : by London standards very good. The flat is less "fresh" than it looks on the pictures 1. Decent size bedroom i.e space around the bed, space for luggage, and proper wardrobe) and quiet (back of the building), good quality queen size bed with nice linen, 2. bathroom is big and water pressure reasonable (shower gel, soap, shampoo, towels available) 3. Living/dining room: fully equipped and can comfortably accommodate 4 people - I can only judge the sofa bed for his seating qualities (a bit hard).
Staircase might be an issue if you carry large suitcases.
Overall very good!
