I had a very comfortable 3 nights in Patrick's apartment. Everything was perfect and as described in the listing. The room is very cosy, the bathroom sparkling clean with a great shower, and you will find everything you need in the kitchen to prepare a meal or just some tea/coffee. Patrick was very attentive throughout my stay and both he and his flatmate (and the very shy cat) were very friendly and welcoming.
As for the location, you will not find better in London. A few minutes walk from the Naval College and other attractions, especially my favourite, Greenwich Park. Greenwich also has excellent transport links to Central London.
I would definitely stay here again. Highly recommended.
