I stayed at Karthik for 10 days ( I was moving to London, so not for holiday ), so I could live Karthik's flat better ...
First it's at 7th floor of a new building so the view it's fantastic! ... Really safe place, any problem about ...
Very well connected with Canary Wharf Tube station (Jubilee Line) ( bus D7 ), so in 6/7 minutes by bus you'll be there ... there is one Lidl supermarket near (in Pixley Street) and a Tesco express, but if you have time you can go also to Asda's superstore in Isle of dogs, 20 minutes by bus (277 or D7), and you can find everything!...
You 'll have the bathroom just for you practically as Karthik have his own in his bedroom ...
Karthik it's a very serious-minded and nice person, good conversationalist and he certainly will give you some tips if you ask for it, as also he know very well London because he have been living here for 17 years ...
Definitely I would recommend to spend time at Karthik's flat because it's a very good value for money, the environment it's safe and really well connected with the centre.
