Location, location, location.
We had a great stay at Michael's place, he was very accommodating with our arrival and his unit has a very comfortable bed and all the utensils you could need, we stayed for a week and were able to walk everywhere, in fact we bought a 4 day metro pass at the airport when we arrived but only used it to get to the apartment on the first day and did not need it after that, as the location is excellent for walking to most of the main areas.
We highly recommend this unit even though the it is small, it is perfect for a visit to the city and we were able to cook our own meals which saved us having to eat out all the time, did I mention how comfortable the bed was :-)
