Great stay for the value. There is 1 staircase to get to any bedrooms and some rooms may be up another floor. If you have serious luggage (I did) and aren't able to carry up 1-2 flights of stairs, I would consider elsewhere. However, as a traveller on a budget I sucked it up, and the fact that the place is a LITERAL 5 minute walk from Euston Station was a big plus. The stairs made up for the longer walk or taxi I would have had to have taken otherwise.
Very clean place when the other guests are respectful as well. Unfortunately I did not have such a pleasant experience with that, but that's not the host's fault at all. The place was very well kept when I arrived and I have no complaints about the room. Very clean and the lock on the bedroom door is very secure, I had no worries at all.
Overall the only thing I found lacking was communication - was a little bit confusing on the guest policy: states that if I had any guests, no matter how long the stay, I would incur the guest fee. I asked if my father to helping me upstairs with my bags would count as having a guest, and she answered with "Of course he can help you," but then reiterated the same guest policy. I played it safe and asked him to wait outside. However this was not a big issue in the end. 4.5 stars if I could do that.
