My parents stayed at Eugenia's place and had a great time there.
It's a cozy and comfy flat where they could rest properly while they were visiting London. Quite central, it's easy to come and go even during the day with the tube station 2mn away from the flat. Eugenia was super available and gave us great tips about things to do during their stay.
And on top of all of that, the view from the flat is stunning! I highly recommend this place for a stay in London, thanks Eugenia :)
