Upon leaving, the host sent a pre-written message that any rating lower than 5 stars is a 'failed visit'. So let's be kind and give it 3 stars. I have seen many Airbnbs and am accustomed to not picking the most fancy locations, but this place was really different from what I expected when booking it.
The building seems deserted, the other half of the hallway is under construction. There, the floor was removed and drilling going on, so the only other people I saw were construction workers. On the side of the hallway of this apartment, all other doors had a keybox on the door, so I think these were also Airbnbs rented out with a minimal level of contact between host and guest. The interior was as cheap as it gets, cold and noisy from the street.
It just felt like a very impersonal way to make money . Cannot judge about the price-quality ratio in comparison to the rest of Riga, but next time I well get something for 5 euro more, if necessary.
