We recently spent a week in London in a newly decorated apartment with all of the required amenities. Location was fantastic, just a few blocks from Chad Thames where there are many choices in restaurants and excellent views of the river and the Tower of London.
Check in and out was easy, we decided to book both to and from the hotel via Nicks Cab which was fun and a great intro to the city as Nick made his way to the apartment while driving close to many of the main attractions.
Access to food was easy, local pub on the corner open till ten, small shop on the corner with most main items, large food shop two blocks away.
Transportation was easy, we used Tower above ground to Greenwich and underground to the city, we also used London Bridge station for variety depending upon where we were going.
Walking was very safe, minutes from the Tower of London, The Globe, the Tate, and across millennium ridge to St Paul's.
If you go you will have a great time, bring good walking shoes and a good camera, there is lots to see and do.
We are thinking of trying this companies apartments in Poland as we found them easy and reliable to deal with.
