We stayed at Essenza Guesthouse for 3 nights. In general it was nice, I would give 4/5 stars.
Pros: Very good location, city centre is reachable within 10-15 mins by bus. A supermarket and some cafes/restaurants in a nice neighborhood. The apartment is very well equipped in terms of kitchen appliances etc.
Cons: There is no proper ventilation at all and the only way to bring fresh air is to open the front door, which is a problem since the apartment is on the street level. The cover on the door is more or less transparent so it needs definitely to be changed cause there is lack of privacy.
Communication and check-in was fine.
