My wife and I landed at the airport around 9AM and Sam let us do an early check in. He was super responsive through text, gave us a few food recommendations when we arrived, and suggested the Argos shop around the corner to buy a power adapter (we're from the US). He even let us borrow a USB power adapter to use throughout our stay.
The location is excellent for the transportation/walk score alone (many other reviews already cover this), but it's superb if you're into Mediterranean food. The whole area is lined with Lebanese and other Mediterranean cuisine.
The only problem I had was the cleanliness level. I don't think the bedsheets were washed when we arrived; it had someone else's odor and I found a few hairs on the bedsheets before we settled in. There was also a patch of spiderwebs at the corner of the bathroom with a friendly little spider that came and went throughout our stay.
Overall it was a positive experience, I would still recommend it to other people. Sam is very upfront about the level of expectation, making sure we were aware during the first engagement that it's a basement-level unit.
