I overall enjoyed my stay at Giba's, though there were some things that weren't ideal. The place is very small, which was expected based on the ad. It was clean, and the room had a little fan and heater which could be used if I wanted, which was nice. He also supplied a towel, which was appreciated. There is a small area with a microwave and small fridge, but there is no plates/cups/utensils, so if you want to eat food or heat up leftovers, etc. it is difficult to do so. There was also noise in the morning and late into the evening (and during the day) which made sleeping difficult at some points. There is a thin sheet provided, but I had no other blankets which I would have liked. The location is pretty good, and it is easy to walk (~30-60 mins) into the central part of London, or take buses (which are basically directly out the front). You also share the space with other people, and I had people knock on my door late at night, which I personally did not want (as I like my private space).
If you are a solo traveller looking for a space that is decently priced and close to the city, then this place may be for you. It is clear that Giba tries to keep it clean, and he was quite friendly to me. However, if you want a relaxing space to recharge, it is very small/has no windows and can be noisy/has no real opportunity to heat up or make food (unless you buy your own plates/utensils, etc). Decide what works for you :)
