I stayed at the Residence Inn Laredo for 10 nights. The hotel staff is extremely friendly and helpful.
The rooms are very comfortable and spacious. A full kitchen with big fridge, freezer, cooking area and washdisher is also included.
The rooms are generally very clean.
The bed is big and the matress is very soft. If you are used to hard matresses it might be a small issue, but I guess you won't find any less soft matress anywhere in the US.
The only thing that was a bit annoying was the loud noise of the aircondition in the room and even outside the room. I could still hear some noises from ventilation shafts outside the hotel if the aircon was switched off. Also the fridge can become quite noisy during night time if you try to sleep.
Another annoying thing was the terrible slow internet speed during evening times. Between 7 - 11 PM I had real problems to access the www - it took 2 minutes to load the google website.
The breakfast was ok. Don't expect a choice thousand different bread types and fruits like you get it in an Asian 4-5 star hotels, but for an American hotel it was good.
I would come back if the city wouldn't be that boring and some sights would be around within the next 2h drive ;-)
Tip: if you need to connect to your VPN, you might get problems in the first and fourth floor. At the second floor everything worked fine.
