Bought our 2-bedroom house in London pretty much near the height of market end-2006. Our timing is rubbish as we thought we would take advantage of the fairly buoyant market summer last year and put it on the market. By the time we got round to doing it (in September), the market had pretty much taken a nosedive. So since then, we have had plenty of viewings but only one (fairly) low offer, which turned out not to be genuine. Of course, we then go and find out dream house, which we put in a low offer on (just under 12%) based on our low offer which didn't work out in the end...). Have been to see lots of houses but this is it. We want somewhere we can stay for a while and this house is big, gorgeously done up (DIY is not our forte) and will see us through till the kids (have two DSs) are at least teenagers or more. This house has not had any offers either though I suspect that has to do with price (if they get asking price, it will break the ceiling for that street). Even agent has admitted it is likely to go for less.
And we have managed to borrow some money off money that will see us being able to raise our offer but we still need an offer on ours to even start negotiating... So now we have had a second viewing on our place last Friday. And agent has called today to organise a 3rd viewing! 
Turns out that it's two retired vicars who are interested: one has now seen it twice and the other only once, hence the third viewing. It's a starter home (target market would be young professionals or young families) though I can see how it could be attractive to them: there's two good size bedrooms and two bathrooms and they are on separate floors so they would have their own 'floor'.
I've kept so calm through the whole process knowing that stressing would not help at all. But I am getting so sick of the cleaning up before the viewings (a nightmare with two small boys), having to accommodate viewing times (tomorrow's is right smack bang in the middle of DS2's nap. which means I have to try and get him down for an early nap and clean the house at the same time!). And getting my hopes up, why on earth would anyone arrange a third viewing if they are not truly interested??!!!! I have been speaking to the agent who is representing the house we want to buy and he is really nice and he knows we are genuine in wanting the house.
If they don't make an offer after tomorrow's viewing, I feel like giving up and just moving DS2 (who is still in with us!) with DS1 into one room and be done with it. We so need the space though... Argh!!!!!!! I am already stressing out about how to work it tomorrow so I can clean the house AND keep two small toddlers entertained...
