I went twice to this mosque in different time and on both occasion it was closed. I don't think it has any regular services but the exterior of the mosque is impressive enough.

К сожалению не знаю и в интернете на нашем языке про это информации нет.

When we went we took the metro late afternoon (it was full, but an experience!) to Nasimi station and came out at dusk. It wasn't obvious how to get there but we found it on foot with a map I'd prepared (it's about a 10 minute walk - a few minutes first to a junction on the main road you come out on, turn right there and walk up the hill on a footpath, again along the main road). It was a bit worrying having to walk around a completely random suburban area of the city as it was getting dark and as usual there were strangers milling around, but we had absolutely no problems going or walking back. Plus the mosque at night is stunning!
