Great value for money but...
The hotel itself if fine, clean and I really enjoyed the complementary breakfast. The location was ideal for me as it was waking distance from shops, supermarkets, restaurants and banks.
The location is probably the main downside. It's located in a busy part of the city, where even some locals wouldn't venture but as long as you don't go walking around by yourself at night and acting like a tourist you'll be fine. There's also the nosey issue, I believe there's a construction site nearby so during the day you'll be kept awake if you're nosie sensitive and at night the sounds of local music may keep you up.
With a stay at Sunrise Hotel, you'll be centrally located in Nairobi, a 9-minute walk from University of Nairobi and 11 minutes by foot from City Market. Featured amenities include complimentary wired Internet access, a business center, and limo/town car service. Event facilities at this hotel consist of conference space and meeting rooms. Guests may use a cruise ship terminal shuttle for a surcharge, and free self parking is available onsite.
