Absolutely recomendable! Both the place and Steve himself are extremely welcoming, you feel like you have your own space but if there's any thing or tip you need, its there. The localization is very convenient, I had anything I needed close in the area (A shopping mall, both a supermarket and a street one, ATMs, even a library), and its one train stop away from London Bridge.
And as advertised, definitely Funky! Also, the bathroom looks out of a five star hotel.
