Raphel was a great, responsive and kind host. He gave me clear instructions for the check in, which went very smoothly.
The apartment's location is great. It was very easy to get from the airport to the apartment by taxi (less than 30 minutes drive and about 20 USD). It is located in the city center, only 10 minutes away on foot from the San Diego Convention Center. The area is full of restaurants and cafes. There is one pharmacy, one Starbucks and grocery stores less than 100 m away from the apartment. The Balboa Park is one touristic highlight and it's at walking distance.
The apartment was spotless! The pictures very accurately reflect what it looks like. The bathroom is big and comfortable. Overall the apartment seems a bit expensive to me considering that it does not have a kitchen or a microwave, which can be inconvenient for long stays. But it is very functional and has cutlery, coffee machine, a nice bed, and everything that is needed for a nice and comfortable stay.
