The apartment is very cozy and perfectly adequate for two people. However, if you want to spend most of the day in the apartment, you should look for a larger apartment. It should also be noted that the breakfast actually only includes the things that can be seen in one of the photos (yoghurt etc are to be obtained yourself). The apartment is in a quiet location, you have good bus and train connections, there are also some options for shopping and dining.
We felt very comfortable!
Since we were in London at a critical time, Gareth kept us up to date and he always answered our questions very quickly :)
