The hosts gave me the larger room for the same price since the smaller one wasn't available. Carol was very kind and helpful with tips on getting around, and also let me run a load of laundry, which was a godsend. It's definitely not a fancy accommodation, but clean and comfortable with everything I needed - comfy bed, fans to keep cool despite the heat wave, hot shower, kitchen, an excellent location close to the bus station and Pimlico Underground, and just a 20 minute walk from Buckingham Palace. There's a great cozy coffee shop too (Cafe Forresti or something like that), about 2 minutes from the flat on Lupus street. Carol also had an excellent book collection, which was an added bonus since I'm one of those people who always feels more comfortable when surrounded by books ...
