We really enjoyed our stay at the apartment and our time in Sevilla. We were a party of 2, staying for 4 nights in late September.
The apartment was spotless, had a fully equipped kitchen (including a washing machine and dishwasher!) and a very comfortable bed. We had no issues with the size, but didn’t make full use of the kitchen. The air conditioning was good, but on hotter nights it struggled slightly to reach the bedroom as it is located in the living room. The terrace was a perfect spot to take in views of the city and is the perfect place to watch a sunset - do note that it is a shared terrace for the whole apartment block and doesn’t have seating etc.
As other reviews have mentioned it is close to the Alameda de Hércules for easy reach of reasonable and nice bars and restaurants whilst also being really quiet and tranquil at night. The rest of Sevilla is walking distance or easily reached by public transport.
