This was a great stay for my family and my sisters family. 3 full bathrooms with spacious showers helped a lot. Ample room for the teenage kids to spread out. Stylish and clean. Also, nice kitchen with washer and dryer. Night was quiet and we slept with the windows partially opened and were not disturbed by noise.
We took a taxi from LHR and asked the taxi driver to wait while I ran up and checked in at the office. It took about 5 min total. That was the biggest drawback.
