I enjoyed my 2 week stay very much. The location is a pleasant 10 or so minute walk to the tourist area streets of Long, St Georges Mall and Adderly as well as the Company Garden, all connecting to Wale Street. The Hilton hotel on Wale Street is less than 5 minutes from the house. I was able to walk to the V&A Waterfront in roughly 30 minutes, which I did several times. The Hop On Hop Off bus is on Long Street and has 3 routes taking you to all the most important sites.
Everything you could possibly need is nearby.
Communication prior to my stay was excellent with clear directions. Gideon was away so I did not meet him but all arrangements for keys, etc. went off without a hitch.
The room is large and private as it is in its own level of the house, the bed comfortable and the bathroom large with a nice shower. The kitchen is large with a family size table. Also a nice washing machine with an outside courtyard to hang clothes; bonus!
There are many homeless people in Cape Town a few of which live near the house. Use of normal street awareness, common sense and compassion were sufficient to be comfortable. Not much different from other cities. I never felt unsafe. If you aren't used to this don't worry too much. Remember, it's the same neighborhood as the Hilton.
I would stay here again in a heart beat and feel very fortunate that Gideon shares his house on AirBnB!
