Marius' place was in a great location - close to many things including the London Bridge station which made it easy to get around. The place is great - as good or better than described - has everything we needed to feel right at home - a great place to come back to after being out.
Marius was very accommodating - even though my data plan kept me from connecting exactly when I wanted to (I live in the US and was roaming in the UK), so I felt bad a few times not being able to respond, or see an entire message until I was in wifi range. He was very understanding and we kept in contact enough to make it a very positive experience.
If you are traveling to London and want to stay near London Bridge area, this is a great place!!!
