Dan's apartment is perfect for two and was very clean. It has a nice shower and comfortable bed and is less than a 10 minute walk from Vauxhall on the Victoria line. It was very easy for us to get around London from his place. There are also fun pubs and tea restaurants in his neighborhood as well.
A company manages Dan's apartment for him, so when I had questions, I could reach someone very easily, however, there was no one there to greet us and we had to walk a few blocks to find the key, which was tricky in the dark.
