I am 32-year-old American and I'm an architectural photographer traveling on business. I travel with a female co-worker from Spain who is an interior designer.
We spend about 2-4 weeks in each city and got a bit tired of the usual hotel scenario. This year we spent time in the US, Moscow, Madrid and Israel.
We are VERY clean, tidy and respectful of the house rules. We are usually out on the job by 9:30 - 10AM and home mid evening. Prefer to cook food when possible rather than eating out all the time which makes this scenario work great.
Also if you'd like, I can take some shots of your place for you to use as a thanks for having us.
