We visited London for a 5-day sightseeing. Selecting Ana's flat was definitely the right choice.
Location:
Connection to London underground is awesome, with just 5 minutes walk to Vauxhall station (from where you'd get to anywhere in London within few minutes). Visiting the key sightseeing stuff - Buckingham Palace, Big Ben, London Eye, Tower Bridge, Leadenhall Market - was easy and with no effort. Sainsbury's local is at Vauxhall station, which served our purpose completely.
The flat itself is opposite a small park, which we used for relaxing (and playing with squirrels). Traffic on street is low, it's a side street.
Only backdraw is that you'd be able to hear the underground tubes in some distance (at least we assume it's the train, there seems to be some air shaft or so somewhere in the street).
Flat:
The flat is exactly as depicted in the pictures. The flat itself is modern and indeed extremely spacious, allowing for feeling quite like home (and not cramped into a small space, likely usually the case in London).
Most kitchen devices - fridge, microwave, oven etc. - are like new with hardly any sign of usage, so actually even tidier than our used ones at home :-)
We are usually very picky with regards to tidyness and cleanness, and with exception of few signs of wear here or there (well, sometimes there are people living in it ;-)) we had no issue or any hesitant feeling at all.
What else is there to say?
Communication/Host:
Ana is very friendly and cares for their guests. We had some communication, which was always easy, timely and hospitable.
Summary:
In our next trip to London, we'd for sure will use Ana's flat again as our base.
