Josephine's room was a lovely and charming space right off of the Clapham North stop. We had absolutely no problem getting around London on the tube. Nightlife and dining in Brixton was also just a short walk away.
Your bedroom at Josephine's will be quite a spacious space on the ground floor. Right outside will be a half bathroom. The shower, however, will be a full flight of stairs up, so take this into account when booking if that would be an issue for you.
For my partner and I, the space was perfect. We had friends local to London, so we spent most of our time out in the day and had a cozy room to crash in when we came back later in the night.
