This hotel thoroughly deserves its current number 1 rating. Spending time there actually seemed to recharge me, whereas a typical business hotel is a bit draining.
PROS: Virtually everything. Spotlessly clean room which is very well equipped. Reliable hot water. Super comfy bed. The grounds are immaculate (good job gardeners!). Breakfast. On site restaurants. This hotel in another city would cost 3x as much. Super safe. Across from the Israeli embassy, so men with AK47s patrol. There is a sign which reads "Nairobi's safest street" -- I believe it!
CONS: I have to strain to list them. The one thing they could improve is service at the front desk. I don't know if it is a Kenyan thing, but several times I came to the front desk and was either ignored or the staff member made eye contact but said nothing. I expect a "Good morning, sir, how can I help you today?" Also I wish the pool stayed open until late. If you work all day and come back to the hotel at 7pm, the pool is already closes. Seems a waste.
When I return to Nairobi, I no longer need to hotel shop. This is the place!!
