I have spent one month in Angeles' apartment and the room. Angeles is a very kind host and is very quick with responding. The check in went also without any issues and Angeles was there to greet me and explain everything in the apartment. Also after that you could always reach her if you had any questions.
The apartment and my room were very clean. The apartment is very nicely decorated. Modern with a vintage touch, for example the floor is still with the traditional Valencian mosaics, which was very nice. You had everything you needed in the kitchen as well as to do you laundry (even washing liquid was provided).
On the other hand I unfortunately cannot say that my stay was a quite and therefore overall a pleasant one. Maybe I just had bad luck, but there was a lot of construction going on, which was why it was loud most of the time. There was construction goin on in the apartment next to my room in the same building, which was extremely loud as the walls are very thin. Also there was construction going on in an apartment in the building across the room as well as road works in the parallel street.
Also due to the garbage containers being right below the apartment, you could always hear the garbage pickup trucks, which was happening almost every day after midnight and sometimes even two or three times during a whole night. As there is no AC in the whole apartment there was no possibility to close the windows, so it was really noisy.
And one Saturday there was a whole fiesta going on in the streets starting at around 11 am and continuing until 3 am the next morning with super loud music and fireworks that were lit in the street.
I also have to add that I was working during my stay from the apartment, so I was in the apartment a lot and not away during the day like a "normal tourist" and was actually relying on the info that the place and street were quiet.
As already mentioned above, there is no AC in the place, which is a big disadvantage. There is a ceiling fan in the room, but it didn't really help or just a little, so as soon as the temperature hits over 30 degrees it gets really sticky and hot in the room and the apartment and as the apartment is on the 4th floor it just heats up and I honestly don't understand why no AC was built in.
So even though Angeles is very nice and the apartment, too, for me personally it was unfortunately overall either too loud, too hot or both and at the end of my stay I was pretty exhausted.
I would therefore recommend the place probably during the cooler months and if you need a really quite place to work or similar check with the host beforehand if there is some construction going on or other things that my cause some continuous noise.
