As the name suggests, this is indeed a cozy place. Coming from the US and having traveled 20+ European countries over the past 10 years (previously all in hotels), we expected a crowded tiny space. Though this place is certainly not roomy as in the US, it was more than sufficient for two adults and an 18-yr old daughter (room + sofa bed). During our 3.5 week visit to Europe (for work but mostly vacationing), we stayed in hotels as well as experimented with several Airbnb. Jeff (the host) was superb - and I mean in every way possible. He went out of his way to ensure that everything was ok and that we were happy and satisfied.
Our first stay was in Porto where the host facilitated two text exchanges - confirmation of check in and check out. More importantly, my daughter stepped on a shattered glass and had a small cut - talk about poor cleaning. All they did was direct us to their first aid kit. Our third stay was in Seville where the host also facilitated two text exchanges of the same confirmation (see a pattern). Our Seville apt was for a space with 10 people between 3 bedrooms. So, each of us had a private bedroom including our 2nd daughter who joined us. Clearly, this place was huge - even by US standards; however, half the place had non-working light bulbs and drains were clogged in both bathrooms. They did address both of these the next day. The funny thing was what they said (not verbatim), "We know about the light bulbs. But what is wrong with the pipes?" Though they did address both of our concerns, I didn't understand why simple change of light bulbs was not performed prior to our arrival, and we checked-in around 9pm. The reason for sharing our other experiences is so that the readers can at least put this review in the context. In short, at least to us, as important as a place is, the host is equally important especially if something does not go as expected. To us, what is important is "prevention and preparation" - that mindset. This leads me to Madrid Cosy Rental's place and Jeff.
Our second stay was in Madrid with Jeff. Place was private and in a great location (< 10 min walking distance to must-see Prado museum), had terrific AC system (record setting heat wave came through during our visit in July), has everything you need including a washer-and-dryer-in-one (a huge plus during our 3.5 week travel), etc. I must say, the most important matter was Jeff, our host. In a foreign country, many things can happen - I knew I could rely on Jeff for anything. I wouldn't be able to put a price tag behind such a peace of mind. As implied previously, I had the sense that my two other Airbnb was interested solely in their businesses. My experience with Jeff is that he sincerely cares about his visitors. For those who may appreciate, I'll offer the following analogy based on my three Airbnb experiences during this trip: Jeff's Madrid Cosy Rental place is to Ritz Carlton or St. Regis as the other two Airbnb are to Fairfield or Springhill Suites - I should know, I am Bonvoy's (previously Marriott) lifetime Platinum Elite member having traveled six continents. Hope this is helpful for those who are considering this place.
