My family and I spent 7 days at this apartment. The terrace is at the roof top and has a very beautiful view especially when it gets dark. Communication was very effective. I guess I was the one who was lost in exploring the city so much that i didn't check messages from the VNG team frequently. Responses were quick not more than an hour.
The second room is small but ok. My kids liked it. For adults it may be a little too small but definitely be managed.
About the comment someone made that taxis find it difficult to locate the apartment, I found what the problem was and I suggested a change to the VNG Property Team. I believe they will effect it as a permanent solution to the problem.
