We stayed at Olga's apartment for a long weekend in Valencia. The location is perfect for easy exploring of the 'old' city by foot but also for exploring areas further away since it is only a short walk to the main train station (Xativa / Valencia Nord), and busses to other areas of the city (including the beach) leave from around the corner. Even though it is in a relatively busy area with shops, bars, cafes, and restaurants the apartment is quiet - even on the weekends! The apartment had everything we needed like coffee maker, kettle, two TVs, shower gel/shampoo, and Wifi. It does also have air conditioning, but it mostly serves the living space. We only really used the apartment for some relaxing at night and sleeping so we would've preferred the air conditioning unit to be in the bedroom rather than the living space since it was hard to cool down the bedroom in the evenings. The apartment was clean, but we did notice an odor from a drain or so in the apartment that should be addressed.
Communication with Olga and her 'team' was great. They reached out proactively and responded very fast to all questions we had. Even when we had an issue with using the front door key late at night, Olga responded within minutes to help us resolve the situation. Olga was also very accommodating and allowed us to check-in early because they happened to not have a booking right before us. This was extremely convenient for us and greatly appreciated. The communication with the person helping us check-in was also friendly and easy.
