Things that were good:
Our stay lasted 7 nights. The apartment is located in a relatively quite area which was easy to get to from the airport. We took the CAT train and then the U4 and it took about 20min. There are a couple of food shops 10min walk away which was handy. And about 20min walk to busier areas. The public transport is great. There is a station 2min walk away which can bring you all around the city. The apartment was spacious and had most amenities.
Not so good.
The apartment is advertised as being "Luxurious", which it might have been some years ago. It needs a lot of attention. I have messaged the host concerning these issues during our stay. Stairs to the upstairs bedroom was very unsafe, Kitchen tap needs repair, blind in the kitchen was not fitted in place, just left by the door. The blackout blinds in the main bedroom could not be closed as there was no way to reach them, the tag attached to the blinds that is used to bring them down was not attached. (Very high ceilings in apartment) Because of this you were awake when the sun came up weather you wanted a sleep-in or not. The patio was not as advertised and was not private. Anyone staying in neighboring apartments can access it. There was a foldout bed which we could not get to stay flat so was useless for us. We noticed a few ants about the place but didn't think too much about it as we were on the ground floor and spent most of time outside the apartment during the day. A few days later my wife noticed the dishwasher was infested with ants. We explained all these issues to our host but our received response was pretty much, meh...
