We stayed in Paula's apartment for four nights in early September.
Communication with Paula before our arrival was good and on the day of arrival our check-in was handled by an agent on Paula's behalf. We contacted the agent when we arrived at Sevilla station and as we walked the 20 minutes to the apartment they were there to greet us and show us in. They recommended some good places and some tips for travel in the wider area.
After check-in we found a cockroach in the shower and the shower had not been cleaned. We informed the agents who quickly sent a cleaner to deal with things. We were also offered the option to move to another apartment but after the issue was dealt with we decided to stay put. This is partly because the location is really good, and we didn't really want to pack up and move our stuff. We were told that cockroaches are quite a common problem in Seville due to the heat.
The apartment is a good size, the bed is very comfortable and the shower/bathroom were fine. The sofa is quite a bit more worn than it looks in the photographs. However it is still comfortable. The kitchen is modern and well equipped, with everything you need to make snacks etc. It's about 5-10 minutes walk through charming backstreets to things like Alcazar and the Cathedral. As a runner I enjoyed the proximity to local parks for my pre-dawn runs.
