My girlfriend and I stayed at this beautiful studio for 5 nights. We originally had only booked for 4 nights, but then we asked Janina if we could stay one more night, and she responded very quickly and arranged everything within a few seconds. Although we didn't have the chance to meet in person, she wrote us all the details about the apartment, always quick and nice, and was happy to assist with everything during our stay.
The studio is in a building with nice 24/7 security guards, and the apartment is secured with two doors. The interior is very nice and spacious. The studio has a very nice view on table mountain. As it's one block from busy Long Street, we sometimes heard a little bit of music, but we didn't care. It might get louder on the weekends, though. We also heard the neighbours partying one night, but our sleep was never disturbed.
There's a very good steak house just around the corner (a little hidden) called "Carne" that we can recommend, and also a very nice burger place called "Royale Eatery". The studio is located perfectly, we did lots of sightseeing by foot, and the next hop-on/hop-off bus station is only 4 minutes away.
It was very nice, we can recommend it to everybody.
