This is the place! We just had an overnight layover between a flight from Dublin and the next morning's flight back to the US and weren't expecting anything special, but Alex and Elmira's place was very special.
The room was meticulously clean, cute, comfy, and stocked with tons of goodies for us to consume. We didn't need to pull out our adapters to charge our various electronics. Banks of outlets with international adapters in place were on either side of the bed. The wifi was strong and fast. They provided a TV and books galore. Great shower! It was so much nicer than the Park Inn where we'd stayed when going the other direction. Did I mention the fridge? and the fact that it's on the ground floor?
There are two very nice pubs within walking distance. We took the city bus, which is free, to and from Heathrow terminal 5 with no trouble at all.
Altogether, it was an unexpectedly delightful experience that I can't recommend too highly.
