The coffee pot had grime in it, the toilet didn't flush easily, if you put anything in the bin instantly colonies of ants gathered next to it. Apartment is around 20min walk from restaurants which we found scary at night. Even though we got very detailed instructions, the apartments are hard for a GPS to find. In the flat description there is a mention of local tax which contradicts with Airbnb policy where tenants should not exchange money outside of Airbnb service. We wouldn't mind paying this tax but because Airbnb advises you not to pay anything outside of the service we didn't appreciate this.
There is not enough sun beds for all apartments, only 3 umbrellas and if all apartments are filled there is not great amount of parking.
Apart from the above we liked staying in Santa Tecla,as it was relative closely to sightseeing spots, apartment was just right for us and we enjoyed having the swimming pool for rest after sightseeing. Lastly, the area was very green, verdant and beautiful to walk around.
