Can recommend staying here if you are visiting London. You can easily reach the City via tube or bus lines. The apartment is very clean and bathroom/kitchen have any amenities you might need, all in a very good shape. Marilena is a kind host, ready to answer any question or give you tips for the local area. She's been in London long enough to know a thing or two ;)
Just be advised that if it does get hot in London (rare enough), the flat also gets hot.
