The location to the underground is brilliant- directly across the street. That is the best feature of this flat. The building felt old and dirty so access in to the apt was a bit grungy.
Inside the flat is dated and has carpet throughout so our kids had itching/sneezing and watery eyes from allergies.
We found the beds to be uncomfortable- hard and palpable springs on one of the kids beds. They are FULL size american beds - not queens- so very tiny and not able to comfortably sleep two people.
The water heater was a hassle but did work.
There were no supplies- no paper towels, no shower gel and no laundry detergent (although there is a washing machine). There is hand soap at every sink which was nice.
Mark was a good host- polite and quick to respond.
Our main complaint is the flat is overpriced for what you get and could use updates- for $450 a night you would expect more.
