Our non profit Stories For Hope Rwanda rented Kacyiru Executive apartments for two weeks, and found it a very good place to stay.
It had all the space we needed to work, and relax, and wonderful views of Kacyiru.
Security is top-notch, and the daily cleaning service was very reliable.
We could order WiFi. Right next door is very full service hotel (still called the Novotel), with restaurants, and pool, and bank. Down the street is the US Embassy.
The only drawback was that the kitchen wasn't fully stocked, if we had to cook. Otherwise, very clean, secure, and attractive space, close to all the Ministries.
