Stayed at Mike's place for a month. A few pros and cons.
Pros: close to transportation, good value, close to shops, nice bed, nice desk and chair to study. Mike is a great host and he did everything to make my stay more pleasant. The first day he immediately resolved an issue with the chair and provided me an extension cord for the lamp on my desk. Also, one night I locked myself out and he responded right away to help me, sending me a new set of keys.
Cons: the room was a little dark, but the lamp helped. The shared bathroom situation depended a lot on the guests, and some were a little less tidy than one wished for. The kitchen had similar issues: the cabinet doors were a bit sticky, and some guests did not wash their dishes properly (at all). During the day the room felt a little cold, as I imagine the heat was not turned all the way. The noise from the downstairs bar was not that much of an issue for me, as it stopped after 11 pm or midnight, depending on the day, but I guess it would annoy more sensitive people. Finally, as an old house, it has a few old house issues, such as a little mouse that was living inside my bedroom wall (this was reported to Mike and I'm sure he has taken care of this by now).
Overall it was an okay stay. I'm not sure if I would stay there again for such a long time, but if you are looking for a convenient and affordable room close to buses and metro, this is a good fit if you are not too fussy.
