Ruth´s place is amazing! The apartment is close enough to the city centre and is literally a few steps from an Underground station, so you can go everywhere very easily.
The place was very clean, the beds are confortable and you have all the supplies that you need for a comfortable stay. There is a laundry machine which is a big plus if you are traveling for a while.
Although we did not see Ruth, the communication with her was perfect and the keys system is very useful because you can do check in and check out independently.
I highly recommend this place!!
