Isabel's apartment is located in a very nice area of Lisbon, just next to Parliament building and to many nice restaurants and bars. The locl "gayborhood" is within walking distance. Communication with host was spotless.
Yet, there are certain aspects to this house you should retain: it's an old building and walls are paper thin. So we could listen to people walking upstairs and people talking downstairs all night long. So, not exactly the best place to rest, if your sleeping is light.
Also, rather inconveniently - at least for us - the toilet was in the bedroom....without any separation whatsoever such as a door. So whatever you do, you it publicly and in the bedroom. So, should you be travelling with someone that you'd not feel, let's say, at ease for such things, you'd better choose another place.
Should you have the need to work, this is not the place for you too.
The quality/price could be better as we felt somewhat above what something like that should deserve. But - truth be told - prices in Lisbon are frankly on the rise and certain prices begin to surpass what you'd except in othe major capitals.
Certain small aspects could help counter such sense that the property was slighty overpriced for what it is: soap in the bath, per example, or a sponge in the kitchen.
Anyway, all in all, its a OK place for you if you're looking just for a place to crash at night after spending your day around Lisbon.
Pros: good location and Isabel's excellent standard of communication and assistance.
Cons: the paper thin walls, the design of the property itself (particularly in what refers to the toilet) and the price/quality balance with quite some room for improvement.
