This was our first stay at Karen's place. It is very easy to find with both the Northern and Victoria Line tubes arriving at Stockwell. There are also a number of buses stopping close by.
The flat itself is on the third floor with no lift access but that does not cause any problems. The lounge and main bedroom face the main road whereas the kitchen, bathroom and second bedroom face the internal courtyard. If you like to sleep with the window open, the noise from the main road can be a little intrusive at night. The flat is comfortable with all the facilities you will need. There is a large Lidl and large Sainsbury's around 10-15 minutes walk away but in opposite directions so if you plan to do any cooking in the kitchen you will find everything you need close by. There are also a number of even closer but much smaller Sainsbury's Local and Tesco Express stores should you need anything urgently.
Access to Central London is very easy by both Tube and bus. If you are foodies, the Northern Line heads straight to Borough Market which is well worth a visit. Southwark Cathedral, Shakespeare's Globe and Bankside are all close to the Market.
It's a good base to explore London but also handy if you wish you some cooking yourself.
We did not meet Karen ourselves as she was away in France but any questions we had were answered very promptly.
