Cesar's home was lovely and in the perfect location to get to know multiple neighborhoods in Sevilla. It felt modern inside, with all the amenities and space you'd need, while still feeling super close to historic Sevilla. My partner and I were working remotely while we were there and had no problem with noise from other units or even from each other when taking calls at the same time, as the unit is spacious enough that noise doesn't travel easily.
The apartment is situated right along the river and within steps of the Puente de San Telmo, so you're no more than 15 minutes walking from most restaurants and major tourist attractions (Catedral de Sevilla, Royal Alcazar, etc.). Just slightly further is the historic center of Sevilla, about a 20 minute walk, incredibly easy to get to. This allowed us to take advantage and still be able to easily explore even while having to work in the afternoon/evenings. Would definitely stay again next time!
