Harry's apartment is a real gem.
It is perfectly situated, close to all the metro lines you will need to get anywhere to the city centre. Yes it is in a calm area, with Thames just around the corner.
The flat is beautifully decorated, has such a soul to it, that it was to us a significant part of discovering London.
Harry was constantly available to answer any questions, was there to greet us and made sure we had everything we needed.
Would definitely recommend it, it was by far the best price/quality ratio as well, compared to other options we were looking at.
