You will love it. Rosa and her husband pursue an unprecedented kind of hospitality. Personally, I had never felt as welcomed as at her place in any other accommodation before. It is literally incredible! You can also get there at ease and it is really not far from the main tourist attractions. I guess it takes you ten minutes to get to Tower Hill station where you can visit Tower Bridge, The Gherkin etc. After all, it's highly recommendable and a place that will feel like your second home.
