Javier is a really great host and made us feel very welcome and comfortable in the apartment. Upon arrival he showed us around the place and showed us a map of the area and recommended places to eat and things to do nearby.
Javier was always easily accessible via Airbnb's message system - his response time was always under 5 minutes and he was extremely helpful when we needed anything :)
The apartment is located in Lavapiés, very close to an abundance of restaurants, a metro station and a big 24h supermarket. We had everything we needed closeby, and we could walk everywhere. The city centre (Sol) was just one metro stop away and of course all of Madrid is accessible with the metro.
As for the apartment itself, we were there during the heatwave of 40 degrees but the temperature inside was pleasant. There are also 2 fans located in the apartment that helped cool us down.
It did get very moist and humid inside, even when we had the windows open, and unfortunately mold was present on the walls. I am very sensitive to mold and got very sick from it, which unfortunately did affect our stay negatively. I was affected by the mold only a few days after arrival but we didn't actually discover it until shortly before departure so unfortunately there was not much to be done.
Javier was very helpful once I mentioned it to him and said he would have the problem fixed.
The apartment had most things we needed. There were some kitchen utensils that would have been nice to have - a bread knife for example - but we got by with the equipment in there. There were basic necessities in the kitchen cabinets, water upon arrival and shampoo and soap in the bathroom.
We had issues with the doors being hard to close, especially the front door, but again Javier was very helpful in solving the issue.
We enjoyed our stay, however the mold issue was pretty critical because it did make me sick and affected our vacation negatively. If the mold issue is fixed we could definitely see ourselves coming back here as Javier is a brilliant host and the apartment is great and central!
