If there is a reason I will remember Hapi guest house in Jūrmala, then probably its green walls and super unprofessional staff attitude will be among top of them.

Hapi guesthouse in Jūrmala

We stayed here for one night back in August 2015 and ... I can not even express my disappointment in words how unprofessional and meanwhile expensive this so called guest house was. We paid about EUR 40 for stay in this place... EUR 40 is not much, I agree - but you can stay for the same price in much more reputable Jūrmala hotels, yes that's right - hotels are not expensive in Jūrmala. Take for example hotel Dzintars (were I stayed a few months prior to stay at this guest house.)

Thus we had a confirmed reservation from Booking.com (and printed) after arrival at this place the person working there( it's hard to call him a receptionist, more some parking guard) informed that all rooms are already reserved, no more rooms for us. I showed him our printed paper, he scratched his nape and took some room keys from a desk. The room he gave us was small, bad ventilated with God knows what anything but bed.

And yes green painted wall made the look even more dramatic.

This place featured a free parking space, but the security guard was literally hunting me asking me to re-park car in other place (thus as you can see there were only two cars). Strange people and very strange guest house. Cannot recommend this time.
