I read a review that stated that Wiriya House is an oasis in the city. I whole heartedly agree... with a big buuuuut.
Oasis in the city, due to swimming pool, friendly helpful staff and prime location, but the hotel itself is quite run down and in need of a bit of modernisation, the worst bring the bathrooms, which were both run down and really unclean. The bedroom was a mosquito murder scene, with months of splats clueing me in to the fact I'd spend my stay wondering how so many got in to the room (cover all the bathroom drains!). The fact that the hotel has painted over some marks in the wall with a slightly different white that the rest of the room only serves to add to the run down effect.
That being said, for €19, the pool was a godsend, you're close to both weekend markets, it's a very quiet, safe location and the staff were so helpful and friendly. A definite recommendation, with a pretty warning about the shabbiness.
