Good value for the money. Well maintained room and facilities, as well as a friendly and helpful owner. The next door shop is very convenient for snacks and drinks at any time of the day.
The nearby tube station (King Cross - St Pancras) offers great connexions accross London. And the British Museum is only 20 minutes walk.
Some rooms are facing a slightly busy road, but not a big issue if you are not a light sleeper (it didn't bother us).
