Location is very good, right downtown. Very clean hotel, with direct access to Al Wahda Mall. The staff is very friendly and reacts quickly to any issues. We had. breakfast and dinner, both not fabulous, but very good
The only minus is the noisy air conditioning and the opening hours of the pool, which is closing too early, at 19:30.
The authorities in Abu Dhabi require PCR test for allowing access to most of the public areas, including for the ones fully vaccinated. The validity is 14 days and you can do it in the Al Wahda Mall for AED 40 per person. Need to install AlHosn app. Usage of VPN is restricted in Abu Dhabi. Whatsapp can be used for text or recorded messages, not for phone calls. You can use Gochat app for phone calls.
SIM cards can be bought in the airport, at arrival. I have paid AED 150 for 22 GB, 50 mins international calls and unlimited locql calls, valid 7 days.
