PubLove may or may not be the best option if you are a tourist — I am a female college student studying abroad in Florence and visited London for the weekend. I found Publove to be a somewhat unsafe environment as many of the people staying in the hostel were older pub guests who were simply too drunk to make it home that night. The beds were comfortable but I found it difficult to fall asleep because of people coming in and out of the room, and it is right next to a busy street. For the entirety of my stay, the bathrooms were without soap. I have definitely stayed in other hostels in Europe that made me feel much safer and cared for.
However, it is very inexpensive and the location is good for the price. It is right next to Edgware Road Station which makes travel pretty easy. The food is 25% off for brunch and 10% off other meals. Publove has perks, however I would not recommend if you are traveling alone or if you are a young woman.
