The host was extremely pleasant and met us near the apartment at the agreed time which was an hour and a half earlier than the stated check in time. We were also allowed to stay a bit later than the stated check out time as our flight back home was a bit later in the afternoon which was really appreciated.
The apartment is centrally located at the northern end of the old town, and is a couple of minutes walk from Torres de Serrano. It is easily walkable to most of the main attractions in town as well as to the main shopping street. We did not use the metro or buses at all, although we did get taxis at night to get to Ruzafa for ease. We also rented bikes to cycle through Jardin del Turia (which is close by) to Palau de les Arts Reina Sofia and the surrounding attractions.
The apartment actually has two bathrooms which we didn't expect when booking, one is an ensuite in the 'main' bedroom and the other is near the entrance. The second bedroom only had one single bed but there were only two of us staying there so that was fine (I suspect another bed is put in depending on how many guests are staying). The shower was not particularly powerful in the main bedroom and the shower screen was not entirely watertight but I understand the apartment was recently refurbished and we were the first guests so these issues will hopefully be rectified. Both showers did not drain quickly and there was an odour after the first day of use from the drains, which should be rectified as I imagine it would not be pleasant in the summer.
The apartment is near a church and the bells do toll every hour during the daytime and every half hour, which can be annoying to some people (especially if you'd like a lie in). There are a couple of restaurants seconds away from the apartment which was handy on the first and last day when we didn't want to travel far.
The apartment was very clean and tidy generally and had all the amenities you would expect e.g. iron, crockery, towels, TV, wifi etc. There is a small courtyard which could be nice in the summer, but we didn't use it due to the time of the year we visited.
