My experience here was mixed. Paloma was great with communication leading up to the stay, the apartment is in a nice residential area away from the tourist area (a positive in my books) and it was very clean and large.
However it was very noisy at night due to the older style apartment with thin walls and floors which means you could hear the neighbors at all hours and it was hard to sleep (this is quite common in older apartments in Spain and southern Europe). The upstairs neighbours kept me up late when they returned after midnight and woke me up early around 7am. They weren't being inconsiderate or partying so it is not something that I could complain about, it was just the sound of them walking, vacuuming, closing doors, cupboards etc (normal everyday things) that were amplified due to the style and age of apartment. I feel this is something potential guests should be aware of, especially if they are light sleepers.
There was no kettle in the apartment so I had to boil water for tea on the stove top, but this may be because in Spain it is less common to drink tea, so it was not a big problem.
There were some minor communication problems with the co-host at the end but it was handled well.
Otherwise it was a pleasant stay in a nice neighborhood and a lovely city. The apartment was a good price with most amenities you need so I would say generally good value and Paloma was a nice, helpful host.
