We've stayed in Montserrat's apartment for a night.
The bedroom is as shown in the pictures in the listing - quite spacious, with a comfortable bed. Having tea/coffee making facilities in the room was nice. The air conditioner worked well, but it is located right above the bed; keeping it in on for the night was not comfortable due to the cold air blowing right over the head of the bed, but with the air conditioner turned off it was too hot to sleep well. There was quite a lot of noise coming from a busy street below, but with the window and shutter closed it was just about okay.
The shared bathroom was very clean.
We've used Montserrat's offer of making a home-cooked dinner at a small extra fee. The meal was very simple, but quite nice and filling.
As advertised, free parking was available in the area. There were some spaces available around 12 noon. There is also a LIDL store within walking distance (<10 minutes walk) and several bus stops for reaching city centre (<5 minutes walk). The area itself was not particularly nice; during the day of our visit there was a severe foul smell, which wasn't however, detectable indoors.
Overall, it was a good stay and Montserrat was very hospitable.
