Definitely not a four star hotel. Unfortunately this hotel was a disappointment, despite the staff being efficient and helpful, and the location also being good. The price is very high for what they offer.
Our room smelled musty, perhaps due to lack of ventilation (there is a small window that opens less than a span). When we arrived, we did not receive the remote control for the television. I called reception asking and they said they didn't know if there was a remote control for our room. At the exit we were asked for the remote control... I justified saying that we had not received and there were no problems.
We stayed two days without internet access in the room (1st and 2nd of November). On the evening of the second day, after complaining for the fourth time, an employee walked upstairs and solved the problem.
The lighting in the room is pretty insufficient. There is only one light for the whole room, making it hard to work at night. A bathroom lamp was burned.
The curtains are not blackout, with the sun entering the room early in the morning. There are large glass windows, but they don't open. There is no air conditioning, only fan.
The bathroom ventilation is completely inefficient, there is no exhaust fan and everything gets really damp.
Apart from the location and the staff, it is not worth staying at this hotel. Look for others, even cheaper, in the same location or in the Zona Rosa.
