I stayed only 1 night at NOVOTEL SOLO, but I think I had great rest there. The hotel staff was very kind, and the manager directly come to my room with his technician of internet when I was complaining of WIFI. The hotel has a cafe in lobby, where offers good decent mood and also delicious cakes & coffee, too. The staff speaks very fluent English, so I didn't have any inconveniences. It is also located in the center of downtown of Solo, so the taxi driver could find the location without any problems.
When it comes to the room, actually the room where I stayed was old. Maybe this hotel is overally old? I don't know well, but it was not so bad 'cause the management of facilities were done good. Clean, comfortable, so it was not a problem. So, I just recommend this hotel to you if you are considering staying in Solo. Might be good choice! :)
