Juli is a terrific host. She was prompt and super-communicative, before, during and after our stay. We stayed for three weeks and worked from the flat.
The flat is well-situated for central London, with easy access to Bermondsey tube (Jubilee line, 10 min walk), the Overground (Surrey Quays, 15 in walk) and multiple busses. You can also walk to Bermondsey Street, Tower Bridge Rd, Maltby St market, and Borough High Street, all within 30 mins. There are numerous food shopping options within walking distance, including a Nisa Local in the same building.
Though it faces a busy street, we had the windows open most of the time and weren't bothered by the noise. The building itself is a bit shabby, but Juli's flat was clean and tidy, and well laid-out. The WiFi worked great. TV reception was a bit spotty (antenna) but not bad. The kitchen has very basic cooking equipment (though no dishwasher). When I enquired about getting some additional bowls, etc., Juli was at my door within 10 minutes.
All in all, it worked out great.
